Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
1) Open System setting
2) Select "Application Style"
3) Select "Window Decoration"

Expected result:
The "Window Decoration" is displayed

Actual result: 
System setting app crashes

Additional info:
I downloaded a couple of Decoration Themes. I belive one of these crashes the
view.
Is there a way to look in som config file which themes are loaded, so I can
provide exactt details?
