Qt Version: 5.5.1
Frameworks Version: 5.23.0
Operating System: Linux 4.8.3-040803-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
opened "System Settings" clicked on "Display & Monitor"
- Custom settings of the application: no, but upgraded nvidia to 370 before (still not rebooted),

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
