Application: systemsettings (5.26.5)

Qt Version: 5.15.8
Frameworks Version: 5.102.0
Operating System: Linux 5.15.0-60-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.26
DrKonqi: 5.26.5 [KCrashBackend]

-- Information about the crash:
Opened system settings -> applications -> File Associations. Performed a search for XML then it crashed. Opened it again, this time I went directly to the xml mime type was able to change the default applications. It appears to crash randomly without any specific action taken.

The crash can be reproduced every time.

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