A corrupted seen file is the only thing that makes sense to me.  If other 
users can open the same folder, then the cyrus.header and cyrus.index 
files must be sane.

As an experiment, you could move your seen file from lang.seen (or 
whatever it's called) to lang.seen.bak.  Then connect to IMAP as yourself 
and try to open the folder.  If it works, then it must have been a 
corrupted seen file, and you can use skiplist.py to recover as much of it 
as possible.

If not...  we can use other tools (strace) to track down the likely 
culprit.
