Unable to create a host group on a new child node

In DM setup when I try to create a host group for a newly created child node, I receive this error:

"Error in query [INSERT INTO auditlog (auditid,userid,clock,ip,action,resourcetype,resourceid,resourcename) VALUES (200100000000005,100100000000001,1329227298,'127.0.0.1',0,14,,'')] [You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''')' at line 1]"
