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:
I've selected another window decoration (changing between Breeze and Oxygen), hit apply button followed by clicking on < All Settings to return to other System settings. At this point the System settings crashes. Reproducible 100%.
Alternatively, it also sometimes crashes if I click on the close (X) button. This doesn't always lead to crash like using < All Settings

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
