Bug 349716

Application: systemsettings5 (5.3.1)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-21-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
Hello! 

I installed Forma-N window decoration and activated it. Now whenever I enter window decoration settings, it crashes.

 Forma-N decoration work well though. 

Kind regards.
