New crash information added by DrKonqi

systemsettings5 (5.23.2) using Qt 5.15.2

- What I was doing when the application crashed:
I did cease observation of "gtk3_preview" and the page that "gtk3_preview" had been invoked from – which was "Gnome/GTK Application Styles" – by switching to 1 different sub-page of the KConfig Module whose identifier is "Appearance" within "systemsettings5".

- Unusual behavior I noticed:
During observation of The Simple Desktop Display Manager during authentication before invocation of "systemsettings5", all custom configuration of it did appear to have been reverted after previous usage of it.
