-- Information about the crash:
- What I was doing when the application crashed:
Booting up and changinp the setting

- Unusual behavior I noticed:
GTK theme always defaults to white. Opening Appeareance settings always crashes.

- Custom settings of the application:
For appearance defaulting all settings and the behavior persists.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
