Application: kmail (1.13.5)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
For the last few sessions, on opening kmail, the default focus has been on an old message that happens to be GPG encrypted; so popping up an 'enter your gpg password' prompt op application open.  (This itself is annoying, since I read the email several sessions ago and haven't wanted to read it since, but it always goes back to it when I reopen the application -- but anyway, that's not what this bug report is about).  I press cancel to the prompt.  I get another one asking me if I want to retry or to press cancel to view the raw, undecrypted message; I press cancel.  Kmail crashes.  (Though not consistently; last time I did the same thing and it didn't).
