It might very well be one still left ;-)

A couple of days ago I suddenly started getting kded4 crashes after I checked 
for upgrades with kpackagekit and found at least one upgrade. As this was new, 
and I had been able to use kpackagekit without any problems since the last 
packagekit upgrade, I started downgrading what I had recently upgraded in other 
packages. However this didn't solve the crash-problem so I re-upgraded again. 
All the time I checked frequently if the kded4 crash still was there and it was!

After much thought I remembered that I had adjusted the KDE system-settings at 
about the time the crashes started. Some experimentation later I found that if 
the "Kpackagekit-tjänst" (-service in english) is started in system-settings > 
Advanced > Services kded4 crashes some ten minutes after kpackagekit is closed 
whether I actually upgraded something or not as long as there are upgrades 
available.

This is fully reproducible. I also have a backtrace but I doubt if it's of any 
use. It's included below anyhow. I use kpackagekit-0.5.2-1.fc12.x86_64.

Regards
Jan
