Qt Version: 5.5.1
Operating System: Linux 4.1.27-27-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Settings->Configure Desktop->Desktop Behavior->Desktop Effects
Select any of the red "film icon" buttons to (presumably) preview the effect.
Crashes ... every time, on multiple workstations.

The crash can be reproduced every time.

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