Having a bad value in the “definition” attribute of the relationship’s entry of the Entity.plist is what probably caused the error. When you recreated it that cleared out the value.
Now, on the subject of a "one-to-one” relationship… Is it a true, bi-directional "one-to-one" where the FK in each table is also the PK? If so, that is not going to work.
