SQLSTATE[42000]: Syntax error or access violation: 1064

SQLSTATE[42000]: Syntax error or access violation: 1064 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 ') < 180, 1, 0)) AS users_user_relationships_is_online FROM user_relationships u' at line 1

This error message displays when I add the user online/offline field to a user view with User Relationship. There is no issue outside UR, such as with users or nodes.

What is strange is that the field settings require a choice between requester or requestee. The view lists all "My Friends" though.

Any thought on the above?
Thanks. :)
