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

Switching to that panel crashes the app, but only in Wayland. The view not affects this as it's when you open that panel.

The crash can be reproduced every time.

-- Backtrace:
Application: Preferencias del sistema (systemsettings5), signal: Segmentation fault
