Application: kontact (4.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0) (Compiled from sources)
Qt Version: 4.6.1
Operating System: Linux 2.6.32.7 x86_64
Distribution: "Gentoo Base System release 2.0.1"

-- Information about the crash:
I wrote and sent an email but made a mistake in the receipient address. So the mailer daemon returned a "Delivery Notification: Delivery has failed" message to me.
In that moment when I try to open this email, kmail crashes.
Every other mail works just fine (I have ~2k mails in this folder and about 10k mails in other folders)

I opened this mail with mutt, where I can read it. It is the standard mail complaning about "Reason: Illegal host/domain name found".

Now I sent another testmail with a wrong domain name, received a "Delivery has failed", klick on it and kmail crashes again.

Then I saved this mail into a file and opened this file with kmail: no crash this time (but still crashing with the original mail)

The crash can be reproduced every time.
