Application: khelpcenter (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:
Openend KIPI Module Video Slide Show and clicked onto button Manual

Other Bugs:
1. digikam totally crashes whitout error message when executing KIPI module Video Slide Show
2. Plasma stops working at all when it is running into the aktual VMware Player 7.1.2 or older versions on different host systems. It runs after installation but about 5 minutes after update the screen becomes black and stay black forever. However the xserver seems to be running. I had to install the xcfe desktop as work around.

The crash can be reproduced every time.
