New crash information added by DrKonqi

systemsettings5 (5.17.3) using Qt 5.13.1

- What I was doing when the application crashed:

Modified various settings, startet with Global Designs and then switched to Plasma-Styles and the application crashed. After a restart I was able to open Plasa-Styles but it crashes often if you clikced 2 different submenues after a successfull launch
