 If you add a custom bulk action to the Media Library:

 {{{#!php
 <?php
 add_filter( 'bulk_actions-upload', function( $actions ) {
         $actions['foo'] = 'Foo';
         return $actions;
 } );

 }}}

 Then if nothing selected when you apply "Foo" (and you have `WP_DEBUG` on)
 you'll get a

 {{{
 PHP Notice:  Undefined variable: post_ids in .../wp-admin/upload.php on
 line 168
 }}}
