Sentry Crash Report:

Description Frans Oilinki 2015-06-02 07:45:04 UTC 
Application: kdeinit5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-18-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
   Right click on menu bar --> More Actions --> Window Manager Settings...
- Unusual behavior I noticed:
   When I tried to change the window decoration (themes), the windows were stripped of all the decorations (window bar and borders missing, no way to control with window manager which window is on top and have focus - maybe window manager stopped running). I changed to Plastik theme (maybe downloaded it using Window Decorations KDE Control Module - I could at the time not see any choices, only Get New Decorations button - It was not immediately obvious that I should resize the window for the currently installed decoration choices to be visible). The only way to get the window decorations and controls working was to log out and log in again.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kdeinit5), signal: Segmentation fault
