Bug 347945

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:

Clicked get new decorations, might have clicked on a decoration and clicked discard.

Every time I click on 'Window Decorations' from 'Application Style' SystemSettings crashes.

The crash can be reproduced every time.

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