Application: systemsettings5 (5.2.2)

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:
In SystemSettings->Window Style->Window Decorations->Crash

I had removed my old .config & .cache and reinstalled kubuntu-desktop.  Some craziness disappeared, but this crash is not affected.

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