Application that crashed: kontact
Version of the application: 4.3.4
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-18-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
At session startup two instances of Kontact open and then crash when I try closing one of them. This bug is probably a duplicate of bug# 185544.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
The current source language is "auto; currently c".
