Comment (by griffinjt):

 Just looking further into this. In wp-admin/includes/media.php, this
 filter is again used. If you do use the correct helper function
 __return_empty_array, you are presented with a myriad of errors and
 issues. This is because `$out` is not defined beforehand and is assumed
 that it will be populated with image sizes. There should be a check to
 ensure $out is actually set and not empty before even creating the Size
 label and associated input fields.
