Sentry Crash Report:

Description Tony 2019-10-26 23:59:23 UTC 
Application: systemsettings5 (5.17.80)

Qt Version: 5.13.1
Frameworks Version: 5.64.0
Operating System: Linux 5.3.6-ck1-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- Custom settings of the application:
Install qt5ct (Qt5 Configuration Tool)
export QT_QPA_PLATFORM_THEME=qt5ct

- What I was doing when the application crashed:
From a terminal run systemsetting5 > Application Style > Gnome/Gtk Application Style.
Doing any change to any of the settings there and hitting Apply witll end up with:

(systemsettings5:30454): GLib-GObject-WARNING **: 19:39:28.307: cannot register existing type 'GdkDisplayManager'

(systemsettings5:30454): GLib-CRITICAL **: 19:39:28.307: g_once_init_leave: assertion 'result != 0' failed

(systemsettings5:30454): GLib-GObject-CRITICAL **: 19:39:28.307: g_object_new_with_properties: assertion 'G_TYPE_IS_OBJECT (object_type)' failed

IF before you hit Apply you go back to All Settings it crashes.

Also tried using the Stock kernel to discard any of the -ck patches interference, i got the same results.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
