Application: kontact (4.4.8)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-35-generic i686
Distribution: Ubuntu 10.04.3 LTS

-- Information about the crash:
To reproduce the bug, I open Kontact, go to Kadressbook, edit and save an address.  Then go to Korganizer, edit a calendar appointment, then return to Kaddressbook.  Kaddressbook shows the most recently viewed Address, but will not allow me to edit the address, or select a different address.  If I continue to try selecting addresses, Kontact crashes.
System Oddities:  I have two Kadressbook databases, and I subscribe to feeds through Akregator.  I have about 20,000 emails stored in Kontact as well.

The crash can be reproduced some of the time.
