Application that crashed: kded4
Version of the application: $Id: kded.cpp 944898 2009-03-26 13:01:25Z dfaure $
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
Can't tell more. I think it is not related to the acknowledging of mandriva update as it also crashes when doing other things.
