Bug 414970

Application: systemsettings5 (5.17.4)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.4.2-1-MANJARO x86_64
Distribution: Manjaro Linux

-- Information about the crash:
- What I was doing when the application crashed:

Looking around in Window Decorations, probably due to an absurd amount of windows themes.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
