Application: systemsettings5 (5.13.2)

Qt Version: 5.11.1
Frameworks Version: 5.47.0
Operating System: Linux 4.17.3-1-default x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:

starting systemsettings5, then selecting fonts

- Unusual behavior I noticed:

at first i could open this part of the settings. after changing settings 'aliasing' to 'enabled', this part of the settings crashes the whole systemsettings5 app

The crash can be reproduced every time.

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