The backuppc-internal rsync can't handle any extraneous messages
before the remote rsync handshake. That is a known problem but usually
triggered by a login message from the remote side.  I thought it would
exit quickly with that error, but maybe it waits for ssh to exit.  In
any case you'll have to find a way to get that message out of the data
stream.   Meanwhile you might try setting up rsync in daemon mode on
the remote side and using the rsyncd xfer method.   That would get ssh
out of the picture.
