Could you please attach some screenshots, because I'm not sure which dialog you are starting and which button you are pressing.
Comment 2 Artur Puzio 2015-12-26 19:07:48 UTC 
Also the backtrace is from version without debugging symbols, so it's not useful for developers. Please install debugging symbols for systemsettings and post the version obtained after installing them. You can learn how to do it here: https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

I have added a screenshot. 

i suspect that an migration from kde4 to kde5 is not realy possible. 
I have deleted so much config files from ~/.kde4/share/ Path and configured it again.

Is now working for you or are you still having problems? If you are still able to reproduce it, please install debugging symbols for systemsettings and post the version obtained after installing them.

Sorry i have no time for installing debug symbols.
In the moment it guess its okay. 

Thank you for your support.
