mutt cannot communicate with archiveopteryx

[apaku]

Hi,

I've send this to the user list and was told that this might actually be a bug. The problem I see is that mutt hangs when trying to open any imap box I have on an archiveopteryx server. Mutt works fine against a locally running dovecot, but also other imap clients work fine with the archiveopteryx server.

I've tried to produce useful debug information using mutt -d2, the generated file is attached (without a few lines about mailbox names that I cannot post here).
