Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I came back to my computer with KMail telling me it lost the server connections (multiple popups for three IMAP servers). Clicking on the top one caused the crash.

 -- Backtrace:
