Comment (by westonruter):

 [attachment:42548.4.diff] ensures that the original `$post->ID` is
 supplied in the call to `shortcode_atts` so that it is available for
 `shortcode_atts_gallery` filters. But instead of passing `0` when there is
 no `$post` it instead passes `null`. If the `null` is then what gets
 returned, the `gallery_shortcode()` function will then short-circuit if no
 `ids` are supplied either.
