Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I repiled to an email hosted in Exchange (accessed via IMAP).  A progress dialog appeared indicating that KMail was fetching the email.  When I clicked "Cancel" KMail crashed.

The crash can be reproduced some of the time.
