Bug 430989

Application: systemsettings5 (5.20.4)

Qt Version: 5.15.2
Frameworks Version: 5.75.0
Operating System: Linux 5.9.16-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 33 (KDE Plasma)

-- Information about the crash:
When I selected to invert the mouse scroll direction the settings application crashed after clicking apply. This has also happened during instances of applying new window styles, theming, etc. This is all with stock options, no additional software installed. This is my first day of using fedora.

The crash can be reproduced sometimes.

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