Bug 374534

Application: systemsettings5 (5.8.4)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.9.0-2-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
 * open up systemsettings
 * go to window decorations
 * click that back button in the top left to get back to the start screen
 --> systemsettings crashes every time

The crash can be reproduced every time.

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