The problem was the Gtid_list event which is logged to the binlog in 10.0 and is not understood by the 5.5 server. This event is supposed to be replaced with a dummy event for 5.5 servers. But the very first event logged in the very first binlog has an empty list of GTID, which makes the event too short to be replacable with an empty event. The fix is to pad the empty Gtid_list event to be big enough to be replacable by a dummy event.
