 Priority:  normal          |  Milestone:  3.4

----------------------------+-----------------------
 `wp_delete_attachment()` relies on attachment metadata when removing
 intermediate images:
 http://core.trac.wordpress.org/browser/tags/3.3.1/wp-
 includes/post.php#L3820

 Since [20435], the metadata is no longer accessible (deleted from both
 database and cache) at that point.
