Hmmm... Unless there is a flaw in my logic for parsing address lists in
the cached envelope, I think you might have a corrupt cache. You might
want to reconstruct the mailbox in question.
That being said, I should handle unexpected input (right now, it gets
into a tight infinite loop). Applying the following patch should fix
the problem, if reconstructing the mailbox doesn't. Sorry for the
nconvenience.
BTW, what IMAP client was using the SORT extension (Pine, some c-client
based software)?
