can you run it from a terminal and paste the error. From the trace I would guess it can't make a GL context and you should check your drivers.
@David: Thanks for the hint. Did some work on checking drivers, let the system finish updating and rebooted. Can't reproduce the error anymore. Leaves the question to me, why the last of my system updates left kde-settings unusable... I change the status accordingly to RESOLVED as I cannot provide an error message as requested anymore after updating. Thank you.
nvidia kernel modules and libGl update together. Anything new loaded uses new libGL with the old kernel and breaks our software. I put in a crash handling fallback in some apps, but not everywhere.
