Same bug of the first post. I think kmail has a problem with incomplete messages. I downloaded the email header with imap. If I don't wait the download of the full mail to complete and delete it or ask to open an attachment then kmail crashes. This should not be an issue, the client should wait and proceed with the requested action when possible. In my humble opinion kmail is trying to access a message that's not yet in the hard disk, memory access violation.
