Version:           Qt: 4.4.3 KDE: 4.1.3 (KDE 4.1.3) KDE Daemon: $Id: kded.cpp 825113 2008-06-27 13:30:46Z dfaure $  (using KDE 4.1.3)
OS:                Linux
Installed from:    Ubuntu Packages

kded4 (KDE 4.1.3) on Kubuntu 8.10 (fully up-to-date) sigsegv'd.
at the time several different things were happening, including
(but possibly not limited to), installing packages (openoffice
from the Kubuntu repositories using Adept), IRC (Konversation),
Kmail, and several Konsole shells (all idling?).

the stack backtrace (which I *just* noticed looks similar to
several other kded4 defect reports — sorry!  I thought it was
different ....  ;-\ ):
