I thought this was wholly to do with my system NAS mounts and just when looking at them, but turns out that it’s not my NAS mounts that have a problem here because I am seeing the same when I navigate to look at /

About 5 seconds after navigating to / i get this popup banner at the top

Current location changed, '/..' is no longer accessible. it also changes the directory/path bar at the top to /../../

I set journalctl to -f and watched. this is the exact error that comes up when the error in dolphin pops up

Sep 03 17:01:29 greg-venusseries kioworker[120762]: kf.kio.core: An error occurred during write. The worker terminates now.

some info in my mounting of root, maybe its relevant.

/dev/nvme1n1p5 on / type btrfs (rw,noatime,ssd,discard=async,space_cache=v2,subvolid=1794,subvol=/@)

I can navigate to ~/ and it does not do it at all?

There does not seem to be any problem if im listing the / (or any folder) in the terminal, im almost sure its just Dolphin.

I am thinking that it has something to do with my btrfs mounts, no idea what though. Have never seen it do this before now (last few days)

Has anyone come across this before? I have searched.

Cheers.

For giggles I checked and I cant seem to get dolphin to complain about this.

But I will mention that it sorta makes sense it would …

.. means ‘parent directory’ … so in /home/jackdinn /../ would be /home/ and /../../ would be / .

From / the path /../../ would be nowhere, or at best, / again, as you cant go ‘up’ any more from root.

It certainly is weird.

Using the terminal at the bottom of the Dolphin window, you can see it trying to cd backwards/up and then doing it again with a double ../
Just odd.

❱ cd /

⎼⎼⎼⎼⎼⎼⎼⎼⎼⎼ / ⎼⎼⎼⎼⎼⎼⎼⎼⎼⎼
❱ cd /..

⎼⎼⎼⎼⎼⎼⎼⎼⎼⎼ / ⎼⎼⎼⎼⎼⎼⎼⎼⎼⎼
❱ cd /../..

Not sure where else to search for logs on the problem apart from the journalctl that i gave above.

I found the problem.
I have a usb bluetooth device that will not re-connect to my earbuds after suspend or at boot etc. So i created a script that uses bluetoothctl to try and connect my earbuds if they are not already. This i run automatically from a timer service.

It never used to cause this problem until quite recently, and i really don’t see the issue but maybe much smarter minds than mine can.
