Text processing/formatting options disappear

After installing this module, the "Text processing" options disappear on textfield and textarea fields. Uninstalling the module solves the problem.

Caused by lines 80-89 in text_noderef.module ? :

/**
 * Implementation of hook_form_FORM_ID_alter().
 */
function text_noderef_form_content_field_edit_form_alter(&$form, $form_state) {
  // Do not allow changing this to anything else besides 'Plain text'.
  $form['field']['text_processing'] = array(
    '#type' => 'value',
    '#value' => 0,
  );
}
