bug on line #38 when used in combination with menu settings per content type module

I'm using your module in combination with http://drupal.org/project/ctm

Works alright when a content-type has ctm permissions, if not then menu_stp throws an error on line #38 because the value is not an array.
I fixed it by adding these lines. Sorry for not posting a patch, can't create one from here!

Cheers

  // add the line below on #38
  if(is_array($form['menu']['pid']['#options'])) {
  foreach(array_keys($form['menu']['pid']['#options']) as $ppid) {
  	if (!isset($mids[$ppid])) {
  	  unset($form['menu']['pid']['#options'][$ppid]);
  	}
  	elseif ($mids[$ppid] == 1) { // sub-tree root, fix title
      $form['menu']['pid']['#options'][$ppid] = _menu_stp_full_title($ppid);
  	}
  }
  }
// add the one parenthesis above
