Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 2.6.41.1-1.fc15.i686.PAE i686
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:

This crash occurs when sending mail using Thunderbird.
Currently I'm using TB8.0 on Fedora15 fully patched at 4.7.3

Its not 100% consistent in that it *always* occurs when I send to the Postfix relay on the mail hub on my LAN bi\ut only sometimes if I send to an external mail server.

Yes, I hate bugs that aren't consistent too ...

The crash can be reproduced every time.
