Application that crashed: kmail
Version of the application: 1.12.0
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.2
Operating System: Linux 2.6.30-ARCH i686

What I was doing when the application crashed:
actual mail message resides on gmail, accessed via imap.  Kmail crash caused simply by clicking on the attachment.  There are a number of possibly related bugs.
