I got a message with two attachments: a big pdf and a short html. I am on slow GPRS connection, but use IMAP. After seeing that the message contains two attachments, I tried to save the pdf. Then, while still downloading, I clicked on the html one. KMail crashed, the progress dialog in the bottom showed two attempts to download the same message.

I got the following backtrace:
