Application: systemsettings5 (5.17.3)

Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.3.11-arch1-1 x86_64
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed: Trying to restore from a wonky installation of an icon theme (Lila-HD).  I was also trying to export / save my current theme configuration just prior to this problem (using the Plasma Look & Feel Explorer).  Now, I attempt to set the system original (Breeze-Dark) and the System Prefs dialog keeps crashing.  Ironically, it seems to have saved my changes back to Breeze-Dark

- Custom settings of the application: Lila-HD Icon set, Airtrim-Dark & Breeze-Dark and the Plasma Look & Feel Explorer were all products in use at the time of this dilemma.

The crash can be reproduced every time.

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