[Evolution] Evo unresponsive on a specific message

["Patrick O'Callaghan" <poc usb ve>]

I have a specific message from the Fedora Test list which gives Evo the
screaming heebie-jeebies. It's a fairly long text message (no HTML) in
UTF-8, Base-64 encoded. I can read it on Gmail with no problem, but Evo
starts burning up cpu and becomes unresponsive. I end up having to kill
it. This is repeatable. Other similar messages don't have this problem.

For the record, evolution-3.8.4-2.fc19.i686, Fedora 19 updated, KDE 4.10

If anyone else is on the Fedora Test list, can they tell me if they have
problems with the following message:

I have the full message saved as an mbox file so I can post it to
Bugzilla if there are no ideas.
