Description vbhunt 2024-03-22 11:24:12 UTC 
Application: systemsettings (6.0.2)

Qt Version: 6.6.2
Frameworks Version: 6.0.0
Operating System: Linux 6.8.1-arch1-1 x86_64
Windowing System: X11
Distribution: Arch Linux
DrKonqi: 6.0.2 [CoredumpBackend]

-- Information about the crash:
I cannot replicate this consistently. Sometimes, after changing some settings for KDE/Plasma6, the System Settings app will crash shortly after clicking the close button on the title bar.It doesn't really bother me, but Dr. Konqui encouraged a bug report, so here it is.

The crash can be reproduced sometimes.

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