_node_reference_potential_references() has been renamed to node_reference_potential_references() in References module (#1154998: Promote _node_reference_potential_references() to the "official" API).
As a consequence, a fatal occurs if a node creation is attempted by Node Reference Create.

Wouter Van den Bosch commentedPomliane posted a nice patch for this issue in this thread http://drupal.org/node/1154660#comment-4503364
/edit: The patch doesn't fix the rename, just the fact that the function now expects a different set of parameters. Applying the above patch and renaming _node_reference_potential_references to _node_reference_potential_references did the trick for me.
