RESTful Server bug with many_many relations

On the wiki it explains that I should be able to use a restful operation in the form:

"GET /api/v1/(ClassName)/(ID)/(Relation) - get all of the records linked to this database record by the given relation".

but this operation won't execute if the relation is a many_many. It seems to work okay as a has_one or a has_many though.

Does anyone have a suggestion? I'm using a daily build of trunk from just a few days ago.

UPDATE

The reason for this bug is an error on line 521 of RestfulServer.php. The
method called getObjectRelationQuery() should return this line:

return $this->getSearchQuery($relationClass[1], $params, $sort, $limit,
$query);

instead of:

return $this->getSearchQuery($relationClass, $params, $sort, $limit,
$query);

Thanks for tracking this down motoservo! So much for consistent API return values... ;)
I've fixed this in trunk with http://open.silverstripe.com/changeset/81346
