Minor I got this error when I tried to create a "conforms to" relation between two documents. I used the search pop-up window.
The document from which I wanted to create the relation already had an incoming relation I had created two minutes before and an outgoing relation to itself (which seems to have been created automatically when I created the incoming relation).
The target document didn't have any relations.
