Hello,
As the title says I’m experiencing many of those errors in various programs since about a month, e.g. krita, telegram, wine, avidemux. Often when trying to save files.
I just ran memtest which said RAM is fine.
Any ideas what could be wrong?
Thanks and greetings,
Jochen
At first glance, possibly a disk-gone-bad – likely your /home partition, if separate, otherwise the main root partition. When attempting to save a file, that area of thie disk is found to be corrupt (aka bad). The fsck tool should be helpful man fsck.
Beyond that assumption, you would need to provide all the usual system information for anyone to help effectively. Cheers.
Hm fsck ran through with no errors except “inode extent tree (at level 1) could be shorter”.
/home is on the root partition (which reminds me that i wanted to move it…)

Tip: When posting terminal output, copy the output and paste it here, wrapped in three (3) backticks, before AND after the pasted text. Like this:
```
pasted text
```
Or three (3) tilde signs, like this:
~~~
pasted text
~~~
This will just cause it to be rendered like this:
Sed
sollicitudin dolor
eget nisl elit id
condimentum
arcu erat varius
cursus sem quis eros.
Instead of like this:
Sed sollicitudin dolor eget nisl elit id condimentum arcu erat varius cursus sem quis eros.
Alternatively, paste the text you wish to format as terminal output, select all pasted text, and click the </> button on the taskbar. This will indent the whole pasted section with one TAB, causing it to render the same way as described above.
Thereby increasing legibility thus making it easier for those trying to provide assistance.
For more information, please see:
Additionally
If your language isn’t English, please prepend any and all terminal commands with LC_ALL=C. For example:
LC_ALL=C bluetoothctl
This will just cause the terminal output to be in English, making it easier to understand and debug.
Something else missing?
Any suggestions?
It seems that a lot of save and open panels are really slow too
I agree with @soundofthunder.
std::bad_allocis the C++ error code for when a new operator tries to allocate something, but fails. As C++ cannot dynamically allocate memory, the lack of memory is the most common cause.
So this:
…makes it look like a disk issue…and you have a lot of drives:
So it could be one of them
Please provide the output of:
df --human-readable
Also, let’s check them for errors. Please provide the output(s) of:
sudo smartctl --all /de/sda
and
sudo smartctl --all /de/sdb
and
sudo smartctl --all /de/sdc
and
sudo smartctl --all /dev/nvme0n1
I’m completely unsure about this, but do a RAM test as well. Check here and test it with Memtest86+:
Memory allocation error – avidemux3_qt…
Try uninstalling Avidemux and Krita:
sudo pacman -S krita
and check the AUR for information pertaining to Avidemux.
However, I’m guessing that if bad sectors are present, it just happens to be where these two packages reside on disk.
… less than I have 
I used to have as many as well. But life happened, and it’s not that many any more…
Five active on SATA, plus a BD writer, and several SSD’s-in-waiting (in removable caddies). None are larger than 1TB (they don’t need to be), except for a HDD for general storage and backup purposes; sized sufficiently to house multiple filesystems. Nothing fancy, but practical for me.
Well, I had a 1 TB, 2 x 2TB, 2(at least, can’t remember exactly) x 80GB, 1 x 250GB and a 120GB external. Now it’s a 4TB SATA, 5TB SATA, and 250 nVME. Oh! And a 250GB M.2 SATA for my Raspberry Pi.
I used to have more drives too, even had to disconnect the dvd-drive to satisfy the need for storage space… (without problems except for weird noises btw)^^
But on this relatively new machine i’d wonder if the drive was the issue, unless its a case for warranty…
The problem has gotten way better by moving /home from the SSD to the 2TB HDD, although there were ~60GB of free space.
But there were some (few) crashes on saving though and the saving dialogues feel slower than they should be still, though not as bad as before.

/dev/sdc is an external drive.
Reinstalling avidemux was no use btw.
Life happening on my drives sounds quite scary, since backing up regularly sucks with ~6 200-1000GB drives fished out of trash PCs^^"
Thanks a bunch
It may not be. Still, it does no harm to check nonetheless.
Is your system updated, and current?
It might be an issue with a common dependency of these apps, such as ffmpeg. Ffmpeg is needed by both Krita and VLC, and there have been issues with ffmpeg in recent days. This will list installed packages that depend on ffmpeg.
pacman -Qi ffmpeg ffmpeg4.4 | grep 'Required By\|Optional For'
Post the output of this command; it may be useful.
Hm,
pacman -Qi ffmpeg ffmpeg4.4 | grep 'Required By\|Optional For'
puts out nothing.
It may not be. Still, it does no harm to check nonetheless.
true…
My system is updated surprisingly often at the moment via pamac.
But i vaguely remember problems with ffmpeg when settting up the machine and less vaguely afterwards (for video editing purposes).
Also VLC tends to crash often when trying to open video files, while mpv doesnt.

You used ‘pamac’, I think.
pamac -Qi ffmpeg ffmpeg4.4 | grep ‘Required By|Optional For’
indeed outputs nothing
Try again, using ‘pacman’ 
pacman -Qi ffmpeg ffmpeg4.4 | grep 'Required By\|Optional For'
Sudo isn’t needed for this query.
~ pacman -Qi ffmpeg ffmpeg4.4 | grep 'Required By\|Optional For' 127 ✘
~ pamac -Qi ffmpeg ffmpeg4.4 | grep 'Required By\|Optional For' 0|1 ✘
~ aeroighaeruighgilhuj 0|1 ✘
zsh: command not found: aeroighaeruighgilhuj
Pamac says that ffmpeg (2:6 0-12) and ffmpeg4.4 from official repositories are installed though.
What do these newfashioned numbers to the right of the terminal mean by the way?^^"
The characters are effectively placeholders, when a font isn’t available to display a given character. Fonts may sometimes not support Cyrillic characters, for example.
If needed, you can change your shell to bash temporarily, if the command doesn’t work as expected on a zsh shell; just type bash.
(You can change it back by typing zsh):
bash
… and try the command again, like this:
LC_ALL=C pacman -Qi ffmpeg ffmpeg4.4 | grep 'Required By\|Optional For'
LC_ALL=C overrides your default language for the output of terminal commands, and outputs in English, hopefully without those characters.
That’s good. What the above command does, is to check which of your installed packages depend on ffmpeg.
Thanks
Weird though, since german characters are not special enough to cause problems usually^^

And i guess except for wine that list includes almost all programs that were problematic.
Looks like it.
Check your mirror status and try to perform another update using pacman:
sudo pacman -Syu
just in case anything new has been added.
Nope nothing.
Do you have a suggestion about what the best way of reinstalling ffmpeg without having to reinstall all depending programs would be?
The issues with wine seem to be solved after replacing wine 7.2 with wine-staging 
As far as I am aware, ffmpeg and ffmpe4.4 were only temporarily downgraded; and the expected versions are now in the Arch repo’s.
I’ve seen mentioned that some mirrors might be slow to catch up though. It would pay to make sure the mirrors you use are all available, beforehand (See ‘Mirrors’ in the menu to the left); and maybe run the following command to make sure you get the most relevant mirrors:
sudo pacman-mirrors --fasttrack && sudo pacman -S ffmpeg ffmpeg4.4
It’s sometimes a good idea to do that when uou update, aswell:
sudo pacman-mirrors --fasttrack && sudo pacman -Syu
