Application: kdeinit5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I wanted to start it by clicking on the "further actions..." option, appearing when clicking the header of any window header.

- Unusual behavior I noticed:
I needed to try this, as K-Menu doesn't open as well.
When clicking on it, a window seems toopen, but doens't appear completey. Stays trsnaparent for just a second and disappears again.

- Custom settings of the application:
Before this happended I downloaded and installed the FormaN (or something like this) theme to change my window decoration.
And I switched the level of how sharp it should be hindered to activate a window accidentally to 'Extreme' instaed of 'Medium' before.

The crash can be reproduced every time.

-- Backtrace:
