-- 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
