Application: systemsettings5 (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.2.1-1-desktop x86_64
Distribution: "openSUSE Tumbleweed (20151002) (x86_64)"

-- Information about the crash:
I added a Window Decoration theme manually, to '~/.local/share/aurorae/themes/', and enabled it via System Settings. Now every time I go to Application Styles -> Window Decorations, System Settings crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
