Description opiuy8 2023-02-18 01:00:02 UTC

Application: kcmshell5 (5.26.5)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.9-200.fsync.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Nobara Linux 37 (KDE Plasma)
DrKonqi: 5.27.0 [KCrashBackend]

-- Information about the crash:
I right-click on the top of an active window, select "Configure Window Manager", and then the window manager opens for maybe 1-3 seconds before crashing. I have 2 applications active: Discord and Firefox. Launching System Settings from the taskbar has no issues, only the Window Manager. I am running Nobara.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
