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:
I suspend my computer at night and wake it up in the morning.  When it wakes up, Kontact complains because it couldn't reach the IMAP servers (I guess it tried to connect before the network came back up).  I dismiss two or three of the error messages, then Kontact crashes.  It does this very consistently.

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