Bug 374999

Application: systemsettings5 (5.8.5)

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:

I changed the window decoration in system settings to a other decoration. Doesnt  matter which one. Foe example breeze was activated and I change to Plastik. Click on Apply.  If I click on the Button "All Settings" in the upper left corner of the settings to move back to the overview of settings, "system settings" crashes. Exactly the same problem when I then move back from Plastik to Breeze.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Aborted
