Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-14-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Chose Application Style->Window Decorations
Fetched aurorae window decorations from the GHNS plugin and chose the air-oxygen decoration. The view stopped responding and after a short while systemsettings5 crashed.

This happens every time I start up systemsettings5 and open Window Decorations.

This is the output when I start systemsettings5 from the command line and choose Application Style->Window Decorations
