Bug 348294

Application: kdeinit5 (5.3.1)

Qt Version: 5.4.1
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I "fixed" my plasma 5.3.1 installation. After an update containing breeze kwin_x11 kept crashing. Eventually I ended up switching to the Qt5 and Frameworks5 repos in yast and it installed cmake and some package with activities 5, then plasma could start again.
Before doing this I changed settings because I was assuming there's an issue with breeze. I installed oxygen5 and breeze5 and ( cannot tell what settings I have set ) changed them to use Oxygen.

- Unusual behavior I noticed:
After kwin started to work again I noticed that although I'm using breeze as theme, the controls are still Oxygen ( the ? | minify | maximize | close buttons ).

- Custom settings of the application:
Cannot say as settings are crashing.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Control Module (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
