Application: systemsettings5 (5.16.0)

Qt Version: 5.12.3
Frameworks Version: 5.59.0
Operating System: Linux 4.18.0-21-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed:
I am using a Microsoft Surface Pro 2 with keyboard cover.  When the keyboard is connected  everything works,  but the touchpad is having some issues.  The touchpad works correctly, but everytime I do a 'click' on it (ie left or right click on a mouse) it does the action but also pops up the touchpad icon with a cross through it.

When I open the Touchpad options from System Settings, the app crashes with the attached errors.

The crash can be reproduced every time.

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