Application that crashed: kmail
Version of the application: 1.12.4
KDE Version: 4.3.4 (KDE 4.3.4) "release 2"
Qt Version: 4.6.1
Operating System: Linux 2.6.25.20-0.5-pae i686

What I was doing when the application crashed:
To reproduce select an email with a big attachment. In my case it was a PDF file.
Click on the attachment and open it with Okular. While KMail is downloading the attachment via IMAP click on it again and select “Save as...”.
Close Okular. When the second download is done KMail crashes.
