 If you call parent_dropdown() and no post has been provided or populated,
 then an E_NOTICE will be emitted in template.php:683 because $post is
 null.

 The fix is to adjust line 681 from:

 {{{
 if ( $items ) {
 }}}

 to...

 {{{
 if ($post && $items) {
 }}}

 I've attached a patch.

 To reproduce:
 1. Ensure that your server is configured to show E_NOTICE errors.
 2. Install NextGEN Gallery
 3. Go to the Manage Galleries Page
 4. Click on a gallery.
 4. Voila. ;)
