dovecot - Feb 2011 - How to recover a mail box from an assertion failure

I'm running Dovecot version 1.2.11 and getting this assertion error on a
user's mail:

Panic: file
/home/durket/dovecot-1.2.11/src/lib-index/mail-transaction-log-view.c: line 290
(mail_transaction_log_view_set): assertion failed: (min_file_seq != max_file_seq
|| max_file_seq != view->head->hdr.file_seq || max_file_offset !=
(uoff_t)-1 || min_file_offset <= view->head->sync_offset)

I realize that there are newer releases of Dovecot (that even may fix this bug)
but what I need to know is if there's anything I can do
(like having Dovecot recreate indexes or whatnot) that will recover the
user's mail (short of having to reconstruct it from backups).

So it crashes in index file reading code.

You can just delete dovecot.index* files from the user's mailboxes.
