Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Ubuntu Packages

Application that crashed: kmail
Version of the application: 1.12.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Tried to delete (not move to trash, but hard delete) an e-mail using the button sequence SHIFT+DELETE. This crash was the result.

It has happened before and I get the feeling that it is timing related and associated with e.g. the reload of an e-mail.
