Application: systemsettings5 (5.17.3)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.3.0-23-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
If I open one system setting category (I have it set to icon view), then another, it often crashes. It does not happen every time, but I can reliably make it crash if I keep trying.

The crash can be reproduced sometimes.

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