systemsettings5 (5.17.1) using Qt 5.12.4

- What I was doing when the application crashed:

I opened the night color setting from System Settings

- Unusual behavior I noticed:

When opening Night Colour as standalone, it doesn't crash. When I openet Night Colour from System Settings the first time, it didn't crashed.

New crash information added by DrKonqi

systemsettings5 (5.17.2) using Qt 5.13.1

- What I was doing when the application crashed:

Simply opening the any of the sub menus in the display options of the settings app causes it to seg fault.

It appears like it's either a Kirigami issue or a QtQuick issue.

According to comment 3, the crash happens here
