Bug 431791

Application: systemsettings5 (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.9.16-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 33 (Thirty Three)"

-- Information about the crash:
- What I was doing when the application crashed:
I click on window decorations or Plasma Style. 

- Custom settings of the application:
I had ddark selected as an Application Theme. The issue reproduces 100% when I am with it and never with my other themes. This theme probably comes from my deepin DE installation. In my opinion it should not be displayed at all in the menu.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
