Bug 482263

Application: systemsettings (5.27.10)

Qt Version: 5.15.12
Frameworks Version: 5.114.0
Operating System: Linux 6.5.0-10022-tuxedo x86_64
Windowing System: X11
Distribution: TUXEDO OS 2
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
I downloaded and applied `WhiteSur-dark`. The starting theme was `Breeze Dark`.
I selected both checkboxes: `Appearance settings` and `Desktop and window layout`.
The `System Settings` crashed when the new theme was being applied. 
I tried to reproduce it going back to `Breeze Dark` and then `WhiteSur-dark` two times and I noticed that:
  1. The theme is applied faster
  2. It doesn't crash anymore

The reporter is unsure if this crash is reproducible.

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