Description Martin Herkt 2013-08-21 12:16:26 UTC 
…or at least that’s what I think is happening. The only hint I have is strace output, since I couldn’t get gdb to attach properly (--nofork didn’t help), and the fact that removing $libdir/kde4/plugins/kscreen made it work.

Reproducible: Always

Steps to Reproduce:
1. Start kded4 on a system without XRANDR.
Actual Results:  
kded4 crashed.

Expected Results:  
It should have made me a sandwich.

The XRANDR extension is missing on my system because I’m using two NVIDIA GPUs with Xinerama to drive four monitors.
