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 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
kmail gets mail from exchange server by imap
search folder shows me inbox messages with "word" in subject
search folder view is standard (nests threaded messages)
used shift-click to select all but the last two messages in search folder
pressed delete key
kmail crashed

this happens sometimes but not always
