dovecot - Oct 2014 - doveadm throws Panic: file dsync-mailbox-tree-fill.c: line 65

Running 2.2.15 on FreeBSD 10.0.

Forcing replication with:  doveadm replicator replicate -f user at host.com
on one user that I've seen some syslogs show up to see what's going on.
Other users are fine.

When I run the above command on the one user it produces a core dump. See
below for syslog output and full backtrace:

Config snippets:
service doveadm {
  drop_priv_before_exec = yes
  inet_listener {
    port = 12345
  }
}
service replicator {
  process_min_avail = 1
  unix_listener replicator-doveadm {
    group = mailsys
    mode = 0666
    user = mailsys
  }
  unix_listener replicator {
    group = mailsys
    mode = 0666
    user = mailsys
  }
}


Anything else I can provide?

Thanks!

What mailbox format are you using? What's the output of:

doveadm mailbox status -u user at host.com 'uidvalidity uidnext'
'*'

Is there one with uidvalidity=0 value? That shouldn't be happening.
