Status changed to 'Confirmed' because the bug affects multiple users.

My error is similar, although starting sup-mail displays old mail initially. sup dies when polling for new messages, so I've reproduced it more simply with sup-sync :-

There seems to be a patch there http://gitorious.org/sup/mainline/merge_requests/12

I wrote that patch, with the intention of eventually shipping it in
Debian/Ubuntu.

However, it has caused some strange issues with sending signed messages
and I haven't had much time to figure them out.

Fixed upstream in Debian (in 2012)
