Comment 1 Christoph Feck 2014-11-05 18:13:43 UTC 
Could you please install -debug packages for kscreen and libkscreen to get a better backtrace?

New crash information added by DrKonqi

systemsettings (4.11.12) on KDE Platform 4.14.2 using Qt 4.8.6

- What I was doing when the application crashed:
I opened "System Settings" and clicked at "Hardware - Display and Monitor"
-debug packages for kscreen and libkscreen are installed now.

I don't know why the backtrace above is "reduced", therefore, I try it again:
