Bug 348669

Application: systemsettings5 (5.3.1)

Qt Version: 5.4.1
Operating System: Linux 4.0.4-040004-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
After installing cupertino-yose aurorae through Get New Decorations and applying the new window decoration and trying it out, I  then subsequently tried returning to change the window decoration, System Settings crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
