Application: systemsettings5 (5.9.5)

Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.11.0-gentoo x86_64
Distribution: "Gentoo Base System release 2.3"

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

When opening the Font Management part in the Fonts section of Systemsettings, Systemsettings will crash.

This is a duplicate of bug #364746, but due to bug #355807, I cannot attach this report to that one.

The crash can be reproduced every time.

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