Bug 370712

Application: systemsettings5 (5.8.1)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.7.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Changing any font in the Font section of System Settings in KDE Plasma 5.8.1 causes the System Settings app to crash. It does change the font, however.

- Custom settings of the application:
I have infinality-bundle installed from "http://bohoomil.com/repo/".

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
