[1]  + 5725 suspended (signal)  systemsettings5




The lines ''file://*' shows when I click on Display and Monitor

The line 'Accessed invalid KPluginInfo object' shows up when a click on Night Color and then System Settings Crashes without showing Night Color configs.

The crash can be reproduced every time.
