I think the problem is mail-search.c is corrupting the index files.

I compiled with -ggdb flag. I'm getting this informations
/var/log/messages: http://pastebin.com/bpkvp4Ak
and from gdb: http://pastebin.com/HY0mVYBS

I'm using mutt for imap access. When I pressed '%' key which runs
<sync-mailbox> function, the dovecot got seqfault.

I tried simple SELECT and it still crashed. As I said, the problem is
dovecot.index files. Somehow, mail-search.c corrupts this file.
