Stack level too deep when collecting relations
Reported by Mike Stenhouse | October 12th, 2010 @ 06:26 AM
While trying to jsonify a collection of objects and include their relations I've stumbled across what I assume is a bug. I've boiled it down to a test case and it seems to be something more fundamental than serialisation.
Test case and a couple of specs are attached. The stack trace looks like:

You can bypass this error by converting the collection to an array before iterating over it.
