Ark 7zip and zip compression not working properly and crashing Dolphin

Hello. Thank you for viewing. After updating my computer yesterday, Ark is not working properly it seems. When I compress files, the ‘Dolphin’ windows, that shows the progress of the compression, never finishes even when the compression is complete. (For 7zip and for Zip)

When I click stop, I get Application Closed Unexpectedly followed by Dolphin CrashingScreenshot_20211019_160411

Did you add 7zip capability? How?
I cannot reproduce with .zip

Is that just in Wayland session?

It comes pre-installed. It is there in KDE I believe if you Right click and go to ‘Compress To’.

I believe I am using Wayland. Honestly, i do not know, as I am not an advanced Manjaro Linux user. I started a few months ago, so I don’t know which session I am using.

Then you are probably in X11 session (default). To check, start Info Center from Application Launcher then see “Graphics Platform” on initial screen.

I am on X11. How do I change it, and if I do, will it fix the problem?

Process of elimination.

  • What happens if you try to only compress a single file with 7z compression in Ark?

  • What happens if you try to compress a small folder (few files only) with 7z compression in Ark?

  • What happens if you try to use “Store” or “Deflate” with the minimum compression strength using Zip or 7z in Ark?

  • What happens if you use ZSTD (Zstandard) with the default (level 3) compression strength?

  • What happens if you wait long enough for it to “really” complete? Does it ever exit cleanly? (Your screenshot shows it is compressing and archive 13,388 files!) :astonished:

  • What happens if you try to compress the culprit folder (13,388 files!) using the command-line instead of Ark? (With the highest / ultra settings that 7z allows.)


I can tell that the command line works. I will do stuff in the order that you have written.

  1. Compressing one file still causes the same error.
  2. Compressing a small folder still causes the same problem
  3. The error persists
  4. Causes Dolphin to crash
  5. I think it completes cleanly. The dialog does not disappear.
  6. Command line works.

Lord have mercy on my soul! As much as I love KDE, they seem to be dropping the ball on their updates and development overall. Has there been a loss of developers? QA testers?

I am facing the SAME EXACT ISSUE ever since the latest update, on two different computers! (I just tested it on on both computers; both recently fully updated on the Stable branch.)

Come on KDE devs…

Every time we update it’s so nerve-racking!


Oh so you have the same problem? At least the command line works. At least we have that, which most Spyware 11 users will not have.

The issue still stands that “rolling” with constant updates on a KDE desktop keeps breaking things more than I remember in the past. It’s like a gamble each time there’s a batch of updates, and you have to cross your fingers and hope nothing breaks.

I have a “notepad” out in which I bump into bugs and crashes and hangs and odd behaviors, which I try to submit bug reports, one by one, but it’s becoming too much of a hassle now. I’m losing enthusiasm, and my hunch tells me that KDE development has different visions and goals going forwards.


Can you confirm if you have any non-ascii characters anywhere in the directory? Because I can’t reproduce this

Single file directly in home folder named avatar.jpg

Right-click → Compress → Compress to → choose 7z format

Even if the archive is successfully created, the progress indicator will hang and “error out” if you try to stop or close it.

UPDATE: It’s a random surprise each time! How fun! Sometimes it will behave as @attishno1’s original post. Sometimes it will immediately abort in failure. Sometimes it will freeze the corresponding Dolphin window in which I need to forcefully terminate Dolphin to get it working again.

I understand. @winnie is actually experiencing the same issue that I am. The archives are being created successfully. It is just that the dialog box never closes. It just stays there.

I have no ASCII characters

It’s hard to tell if this is a KDE Frameworks or lower-level bug, or if it is Ark (or Dolphin) itself that is at fault. :man_shrugging:

The command line is working 100% though.

Apologies, I reproduced this on my second attempt. Sadly command line output is useless

[daniel@daniel-systemproductname ~]$ dolphin
Segmentation fault (core dumped)
Thread 1 "dolphin" received signal SIGSEGV, Segmentation fault.
0x00007ffff5eaa521 in ?? () from /usr/lib/

If I leave it alone without trying to stop or close it.

UPDATE: It works fine if Dolphin is bypassed.

If you manually add folders and files into a new archive (using Ark itself, not the Dolphin context menu), it behaves normally, regardless of size or number of files. The progress indicator in the bottom-right corner will behave normally as well.
