Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

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

- currently using the default "Breeze" window decorations theme
- want to change the font for the window title and/or change to different theme
- crashes as soon as I switch to the "Window Decorations" configuration option

The crash can be reproduced every time.
