Description Avery Freeman 2021-03-06 04:32:39 UTC

Application: plasmashell (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.11.0.zfs x86_64
Windowing system: X11
Distribution: Debian GNU/Linux bullseye/sid

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

- Unusual behavior I noticed:
Startup animations slower than usual. Once taskbar area usually appears, now goes blank and bug report window opens.  No windows, etc. present, desktop inaccessible.  Appears to happen every time - have reproduced 5 times now.  

- Custom settings of the application:
Using self-compiled vanilla 5.11.0 kernel.

The crash can be reproduced every time.

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

Comment 1 Noah Davis 2023-08-09 15:59:42 UTC

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can you please check if this is still an issue with Plasma 5.27?

No KDE code is implicated in what I can see from the backtrace, and the backtrace has no debug symbols for anything that would help. :(
If this crash is reproducible, could you please install debug symbols, reproduce the crash, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks!
