Description the_archer_xz 2023-08-09 12:16:38 UTC

Application: plasmashell (5.27.7)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.2.0-26-generic x86_64
Windowing System: Wayland
Distribution: KDE neon 5.27
DrKonqi: 5.27.7 [CoredumpBackend]

-- Information about the crash:
It seems to occur rather frequently with plasmashell crashing when attempting to clear the clipboard. But other random crashes occured as well when doing various things. But the clearing of the clipboard causing plasmashell to crash is a typical issue with this version of KDE Plasma it seems. And I don't know if this is specific to Wayland only.

The crash can be reproduced every time.

DrKonqi auto-attaching complete backtrace.

I strongly suspect that this bug is no longer possible to experience in the upcoming Plasma 6 due to changes in the code that's crashing here.

Comment 3 the_archer_xz 2023-08-09 20:07:36 UTC

Well, I have no idea on how to code. So, I am leaving this to the experts. 
Hopefully the bugs will be fixed in Plasma 6 regarding plasmashell crashing 
though.

I finally managed to make drkonqi generate a backtrace. Before, it was failing 
to do that for some reason whenever plasmashell crashed.
