Bug 213279

Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
When logging in with an instance of Kontact in the saved session, another one tries to start, generating a warning. Clicking "Start Kontact" on the warning opens two instances. Closing one of these instances causes both to crash.

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