Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-ARCH i686

What I was doing when the application crashed:
This happens every time I do the following:

* Change to a folder for which the selected message requires a pgp password to be decrypted (password not stored)
* Select another message before the (modal) prompt for pgp passphrase appears (this happens very often when I get new mail: the previous one is selected by default, and I select the new one to see its content before realising I should have waited for the prompt )
* Cancel the request for a passphrase (to close the modal dialog)
* -- That's where Kmail crashes.
