[Dovecot] doveadm segfaults on TCP connect - version 2.0.15

[ghandidrivesahumvee at rocketfish.com]

Hi list,

I just recently installed Dovecot 2.0.15. Unfortunately, doveadm segfaults
when I attempt to connect to the local dovecot instance. When this occurs,
my logs show:

2011-10-19T12:31:23-07:00 mail02 dovecot: doveadm: Error: doveadm client
not compatible with this server (mixed old and new binaries?)

I am using the settings listed on the wiki page
http://wiki2.dovecot.org/Director

[root at mail02 ~]# /opt/dovecot/bin/doveadm who -a 10.10.5.220:544
Segmentation fault (core dumped)

doveconf and gdb output are below. If there is any more information I can
provide please let me know.

Thanks!
