Public bug reported:
I've updated my Kubuntu system from Precise Pangolin to Quantal Quetzal
12.10. The update went smooth. However, I now consistently get a
segmentation fault in kded4 or kdeinit4 (one or the other) after I've
logged in (using the graphic login). I can repeat this consistently by
logging out and logging in again (without restarting my machine).
This is the information which I get for my crash (unfortunately, there
are no additional debug symbols available for installation, it seems):
Application: KDE-Dienst (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

This still occurs even if I rename my ~/.kde/ and ~/.kderc before
logging in.
