 `multi_resize` is not properly checking for `WP_Error` after a save before
 dereferencing the metadata returned from _save().  This can cause a fatal
 error (due to dereferencing a `WP_Error`) if one of the individual saves
 fails.

 This is a regression to the previous behavior in 3.4.2

 Patch attached fixes this by moving the array access/unset into the `!
 is_wp_error()` check.
