I tried this Andrej, but it still crashes, the behaviour is slightly
different though, the email reaches about 75% downloaded and then
crashes with some of the rendering already done, previously the crash
occurred without any rendering done and seemed to happen after the
download bar had disappeared.

I don't know what else I can do but you are welcome to ask, currently I
don't think I have any debug dlls loaded.
