New crash information added by DrKonqi

systemsettings5 (5.19.3) using Qt 5.15.0

- What I was doing when the application crashed:
Open SystemSettings.
Enter a category page.
Change a setting on some modules, or even no change on other modules.
After Apply (or not if nothing changed), click Back main button.
Immediatelly crashes.

Note that this does not happen on some modules.

- Unusual behavior I noticed:
Nothing unusual apart from this crash.

- Custom settings of the application:
All are official packages and normal usage.
