return 404 when adding node in certain conditions

Hi everybody,

I found a bug in noderelationship : appear when we want to add a node in a "Node reference CCK field" in certains conditions.
Iit's a similar issue as http://drupal.org/node/943564

I have two contents types (CT1 and a CT2) that can be referenced in a CCK field (via node reference) in a CT3.
A "user A" can create both CT1 and CT2.
A "user B" can only create CT1 or can only create CT2.

For "user B", that result by a drupal_not_found() in the noderelationships_noderef_page() function.
For "user A" => no problem.

This happens due to noderelationships_noderef_page_create(), at lmine 398

      if (count($node_add_list) > 1) {
        return theme('node_add_list', $node_add_list);
      }

is this case ("user B"), count($node_add_list) = 1.
After this code, there is a drupal_goto(), but it isn't called (use to go to the node add page)
This is due to the $new_type that isn't defined properly (due of foreach() before)

I Modified the code like that

      if (count($node_add_list) > 1) {
        return theme('node_add_list', $node_add_list);
      }
      // There is only one content type we can create
      else {
        // Redefine $new_type, cause of foreach ..
        $merge = array_intersect($reference_fields[$field_name], $creatable_types);
        if (count($merge) == 1)
          $new_type = $merge[0];
        else
          return theme('node_add_list', $node_add_list);
      }
    }

Sorry for my poor english, hope this can help someone !
