Bug 358380

Application: systemsettings5 (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160120) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
1) open Systemsettings
2) change something (no matter what)
3) switch to other option-tab
4) discard the unsaved changes
5) close systemsettings

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
