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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
