Table mysql.ndb_binlog_index contains no data (no replies)

hi,

I set up a new MySQL-Cluster (v7.1.5) with 4 Data-Nodes, 2 SQL-Nodes and 2 MGM-Nodes on RHEL 5.5 (64Bit). The Cluster itself works fine. Now I try the Point-In-Time Recovery using mysql cluster replication. I can create a backup and restore it. The only problem i have, that the table mysql.ndb_binlog_index is empty.
Has anybody an idea why this table contains no data?

thanks
