13905	No sanity check in map_meta_cap caps throws PHP notices	filosofo	filosofo	"`map_meta_cap` assumes that the ID which it's passed when evaluating `edit_post`, `edit_page` and the like actually belongs to a real post object.

In fact, it's quite possible that the object doesn't yet exist (creating a new object, perhaps) or doesn't exist any more (deleted), or that it has otherwise received a syntactically correct ID value that doesn't map to an existing post object (0, e.g.).

Instead, `map_meta_cap` should check that the post object actually exists before attempting to branch on its properties.

Patch also removes some apparent debugging comments."	defect (bug)	reopened	normal	Future Release	Post Types	3.0	normal		needs-patch	kevinB
