Application: systemsettings5 (5.3.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-28-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed: It's the same as several other previously reported ones, but the button to inform that was ignored.

- Custom settings of the application: Oxygen decorations. Cannot change it now, because it crashes all the time.

The crash can be reproduced every time.

-- Backtrace:
Application: Configurações do Sistema (systemsettings5), signal: Segmentation fault
