Sentry Crash Report:

Description jujik 2020-10-26 23:30:15 UTC 
Application: plasmashell (5.17.5)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-3-amd64 x86_64
Distribution: Debian GNU/Linux bullseye/sid

-- Information about the crash:
- What I was doing when the application crashed:

So I just set the auto-login via Plasma/wayland; every app got restored from my previous session. I have Dark+Purple Theme

- Unusual behavior I noticed:

even with clean desktop (no apps left, with every app closed on the prev session), Plasma/Wayland crashes on SimpleMenu activation (as I have taskbar vertical on the left).


The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Crashing somewhere in KWin:

If you're still able to reproduce this, could you please attach a new backtrace with debug symbols?
Comment 2 Vlad Zahorodnii 2021-02-25 09:12:43 UTC 
Nope, the window system integration plugin is not part of kwin. 5.17 is a quite old version. It's worth checking if the bug is still present in 5.21.
