Application: systemsettings5 (5.10.2)

Qt Version: 5.7.1
Frameworks Version: 5.35.0
Operating System: Linux 4.10.0-22-generic x86_64
Distribution: KDE neon User Edition 5.10

-- Information about the crash:
- What I was doing when the application crashed: Simply going > System Settings > Input Devices > Advanced tab > Press Configure keyboard options, leads to crash and KDE Neon asking for bug report due to segmentation fault	

- Custom settings of the application: Wayland instead of X11

The crash can be reproduced every time.

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