dovecot - Jan 2013 - dovecot nightly 20130117: dsync does returns "Name or service not known"

Hello.

I have this settings of imapc:

# doveconf -a | grep imapc
imapc_features imapc_host imapc_list_prefix imapc_master_user
imapc_max_idle_time = 29 mins
imapc_password imapc_port = 143
imapc_rawlog_dir imapc_ssl = no
imapc_ssl_ca_dir imapc_ssl_verify = yes
imapc_user = %u

and try to sync mailbox on old server and new one:

$ dsync -o imapc_user="user at example.org" -o 
imapc_password="pass"  -o
imapc_host=imap.example.org -o imapc_features=rfc822.size -o
mailbox_list_index=no  backup -R -f -u "user at example.org" imapc:

get this error:

ssh: Could not resolve hostname remote: Name or service not known
dsync-local(basov at megagroup.ru): Error: read(remote) failed: EOF
dsync-local(basov at megagroup.ru): Error: Remote command returned error 255

In this time new dovecot finds local user:

2013-01-17T17:21:29.837415+04:00 imap1 dovecot: auth: Debug: userdb out:
USER#0111#011user at
example.org#011home=/var/vmail/example.org/user/#011quota2_rule=*:storage=40M#011nodelay=Y#011uid=999#011gid=999

I don't understand what's mean under 'hostname remote'. What
hostname?
Is it bug or incorrect settings?

More debug ouput:

$ dsync -D -v -o imapc_user="user at example.org" -o 
imapc_password="password"  -o imapc_host=imap.example.org -o
imapc_features=rfc822.size -o mailbox_list_index=no  backup -R -f -u
