Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I clicked Login Screen (SDDM) under System Settings. It crashes everytime.

- Unusual behavior I noticed:
Selecting the Breeze Dark theme, panel did not change colour, Kmenu icon,
system tray icons and time date not visable.

-OS used and hardware
New install of Kubuntu 15.04, updated as of today. Running on an Apple 8,2
Macbook Pro (Early 2011) - intel 2nd gen i7, AMD Whistler [Radeon HD 6640M],
16GB RAM. EFI booting.

The crash can be reproduced every time.
