Sentry Crash Report:

Description Sam Azer 2021-12-31 18:16:09 UTC 
Application: plasmashell (5.23.4)

Qt Version: 5.15.2
Frameworks Version: 5.89.0
Operating System: Linux 5.3.18-57-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.3"
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
On this occasion I wasn't actually using the computer for a few minutes. There are quite a few software packages running (ie: Thunderbird, Firefox, Remote-Viewer, Ksysguard, Dolphin, Virtual Machine Manager.) I was writing some notes in Kate but then stepped away. When I came back I clicked on the task bar and Plasmashell crashed and restarted.

- Unusual behavior I noticed:
On this occasion the taskbar / plasmashell crashed and restarted when I clicked on it (pretty sure I was clicking on the NoMachine icon in the icon tray on the right.)

Sometimes it just locks up by itself randomly. In those cases I killall plasmashell; kstart5 plasmashell.

On this occasion the crash reporting assistant did open (most often it does not.)

Note that this seems to happen randomly. I'm not aware of a keypress or mouse sequence that will allow me to reproduce this bug at will but it does happen.

- Custom settings of the application:
Using Packman and a number of KDE repos for OpenSUSE (+more.)
Using the old task manager (not the new one with the icons only.)
Using the latest NVIDIA drivers (470.86)
Using the Tiled Menu instead of the new Kickoff menu.
Using BTRFS for all the filesystems.



Thanks again, Happy New Year.

The crash can be reproduced sometimes.
