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: 4.5.3
Operating System: Linux 2.6.31.12-174.2.19.fc12.x86_64 x86_64

What I was doing when the application crashed:
I open kpackagekit searching for some application to uninstall. The application (Autoscan network, recently instaled via its own installer tool) was not found, and i close kpackagekit, and continue browsing normally with opera.
bug reporter appears suddently but I were working normally (for my appreciation, kpackage kit was closed without incidences).
