Description seplexfake 2021-02-01 09:04:42 UTC 
Application: systemsettings5 (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.9-1-default x86_64
Windowing system: X11
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:
I have installed custom cursors.
Applied the installed cursors.
Restarted the settings app.
And deleted the cursors. (not from the store,  but from the cursors menu in settings)

- Custom settings of the application:
I have a bunch of themes, maybe it's my fault

The crash can be reproduced every time.

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