Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed: changing the decoration aplications.

- Custom settings of the application:  i use some decoration from kde-4.  I updated kubuntu from kde 4 to plasma 5.

The crash can be reproduced every time.
