What does that mean? WHY has the Message-Id been lost? How can I find out WHICH MAIL caused this?
Can you reproduce it? I'm guessing dovecot.index.thread file was corrupted and caused this. It should probably rebuild the thread if this error happens.
Or if you can reproduce this without dovecot.index.thread then it's definitely a bug and I'd like to get some headers to reproduce it:
doveadm fetch -u user@domain 'hdr.message-id hdr.in-reply-to hdr.references' mailbox INBOX
Anyway, improved the error message: http://hg.dovecot.org/dovecot-2.2/rev/5de1e4fdb758
