Bug 346863

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:
This is Kubuntu 15.04.

I've installed some Window Decorations within the System Settings. After adding some and closing "Get New Stuff" dialog the System Settings dialog crashes on redisplaying the Window Decorations.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
