Application that crashed: kontact
Version of the application: 4.3.3
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic i686

What I was doing when the application crashed:
When network connection is lost while being connected to an IMAP server, Kontact/KMail displays error messages, and crashes directly after user discards those messages.
