New crash information added by DrKonqi

systemsettings5 (5.17.2) using Qt 5.13.2

- What I was doing when the application crashed:
When opening the window decorations section my system settings crashes and it is happening quite often. I have all my updates applied on stable Arch.

systemsettings5 (5.17.3) using Qt 5.13.2

- What I was doing when the application crashed:
Opening window decorations causes the systemsettings to crash. This happens to me 3 out of 10 times. It happens when opening that section in the settings. You do not have to change window decorations just open that section.
