Was checking various system settings and closed the window pane for it and error popped up. Couldn't find this error in here with search...

The same issue happened in OpenSuse Leap 42.1 but was fixed. https://bugzilla.opensuse.org/show_bug.cgi?id=951933

If you go to K icon in bottom left to open menu, click "configure Desktop" icon in left panel, it opens up fine. I then clicked "Power management" under hardware settings section (didn't do anything specific). In top left clicked on "< Overview" (back) link. Then clicked on "Display and Monitor" setting /icon, to view "Display Configuration" settings there (didn't do anything specific), and then again clicked "< Overview" (back) link, and then get that error over and over again. Doesn't seem to happen with other things though...

Relates to KDE version of Kubuntu Wily, not Gnome version... I believe this output is same from Kubuntu Wily as it is in OpenSuse Leap...
