Create New Page drop down empty

When creating a new page for a new gallery, the drop-down for “Create New Page” does not display any pages. This removes the ability to make the gallery page a child of one particular page.

This is solved by commenting out the if statement in /admin/mange-images.php on line 340ish:

<?php //if (get_post()): ?>
<?php parent_dropdown (); ?>
<?php //endif ?>

Each time I update the plugin, I have to go and comment out this if/then. It has been going on for several versions. Can anyone help?
