Application that crashed: kded4
Version of the application: $Id: kded.cpp 1031638 2009-10-05 16:59:11Z lunakl $
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I had a few apps up and was typing in emacs.
Something crashed and put up the crash reporting assistant.
I slogged through the traces, downloaded the debug versions of the libs that didn't have debug info.

NOTHING IN THE TRACES TELL WHAT CRASHED! HOW USEFUL IS THAT?

 -- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Segmentation fault
