Application: systemsettings5 (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

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

I tried to change the window decoration. Changing the default window decoration to any downloaded one usually works. But when I want to change it again it the settings dialogue will crash. This happens in both, Plasma 5.2 from Kubuntu 15.04 and Plasma 5.3 from the KDE website.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
