[Dovecot] Abort error in current CVS version

[Todd Burroughs]

I just tried the latest version from CVS and got this error:

dovecot: Mar 29 18:11:33 Error:  27526 IMAP(todd.bluegenesis.com): Corrupted index cache file /mailhome/new/t/b/todd.bluegenesis.com/.imap/INBOX/dovecot.index.cache: Duplicated field in header: hdr.RESENT-TO
dovecot: Mar 29 18:11:33 Error:  27526 IMAP(todd.bluegenesis.com): file index-mail-headers.c: line 68 (index_mail_parse_header_finish): assertion failed: (match[match_idx] != mail->header_match_value + 1)
dovecot: Mar 29 18:11:34 Error: child 27526 (imap) killed with signal 6


I deleted the index files, didn't help.  I checked my mailbox and there
aren't any mails with a duplicate "Resent-To" header.  With older
versions of dovecot, I still get this error, but it does not abort.
(Using mbox, if it matters)

Here's a backtrace:

Core was generated by `imap'.
Program terminated with signal 6, Aborted.
