postgresql-9.4-BDR replication issue

Hi all.

I've installed postgresql-9.4 with BDR from its official repository, and
trying to create replication group with database on two nodes:
on first node runned:
CREATE EXTENSION btree_gist;
CREATE EXTENSION bdr;
SELECT bdr.bdr_group_create(local_node_name := 'node1',
node_external_dsn := 'host=10.10.1.39 dbname=bdrdemo2');

on second node runned:
CREATE EXTENSION btree_gist;
CREATE EXTENSION bdr;
SELECT bdr.bdr_group_join(local_node_name := 'node2', node_external_dsn
:= 'host=10.10.5.107 dbname=bdrdemo2', join_using_dsn :=
'host=10.10.1.39 dbname=bdrdemo2' );

And then getting this error on second node:
< 2015-05-25 03:38:37.714 PDT >LOG: starting background worker process
"bdr db: bdrdemo"
< 2015-05-25 03:38:37.731 PDT >ERROR: previous init failed, manual

< 2015-05-25 03:38:37.732 PDT >LOG: worker process: bdr db: bdrdemo
(PID 25402) exited with exit code 1

I've tried to remove all replication slots on both nodes:
select * from pg_replication_slots;
select pg_drop_replication_slot('replication_slot_name');
tried to clean bdr.bdr_nodes, bdr.bdr_node_slots and bdr.bdr_connections,
tried to drop database and create it again - all was useless.

What's missed?

Thanks.
