New crash information added by DrKonqi

systemsettings5 (5.20.5) using Qt 5.15.2

- What I was doing when the application crashed:

Changed the wallpaper for the lockscreen. Clicked apply, and closed the settings window. Crash popped up but the setting is applied since the new background is correctly set.
