New crash information added by DrKonqi

systemsettings5 (5.22.4) using Qt 5.15.2

- What I was doing when the application crashed:

Either adding a new virtual desktop or changing anything about an existing one (eg changing its name) and clicking the Apply button will crash the settings dialog (the change will be abllied though).
