#30991: Post type object capability 'delete_posts' is referenced in the posts list

 I'm getting the following error when viewing the main edit screen of a
 custom post type:

 Undefined property: stdClass::$delete_posts at wp-admin/includes/class-wp-
 posts-list-table.php:209

 When I looked up the line, the following code is run:

 {{{
 if ( current_user_can( $post_type_obj->cap->delete_posts ) ) {
 }}}

 The problem is that the capability, 'delete_posts', is only applied to a
 post type (via get_post_type_capabilities()) if the 'map_meta_cap'
 argument is set to true when you're registering the post type (via
 register_post_type()).
