Bug 345894

Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-12-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
In the KDE settings I choose "Alkalmazások megjelenése" in HU translation (Appearance of applications in direct translation), and then I select "Ablakdekorációk" (Window decorations in direct translation)
systemsettings5 crashes with SIGSEGV

The crash can be reproduced every time.

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