node_form not found when attaching a video.

After upgrading to the latest version of Media and File Entity I can not use the attach button on the node edit page after picking a video. The ajax callback pops up this error:

An AJAX HTTP request terminated abnormally.
Debugging information follows.

ReadyState: undefined

I managed to solve this for my use case by adding the following line to media_ajax_upload() just before the call to drupal_process_form() :

module_load_include('inc', 'node', 'node.pages');

As described in http://stackoverflow.com/questions/14252779/drupal-node-form-undefined-f... . I don't think this solution will work for every situation though.
