#19814: add_theme_support() inside init hook function breaks post attachments

 Priority:  normal         |  Milestone:  Awaiting Review
Component:  Media          |    Version:  3.3.1
 Severity:  normal         |   Keywords:  needs-patch
---------------------------+-----------------------------
 When adding post-thumbnail support to a theme via add_theme_support(),
 inside of an init hook function, the post media attachments no longer
 work. Simply placing the add_theme_support() call outside of the init hook
 function corrects this. See attached screenshots for display of the issue.

 <?php
         //WORKS - The 'Add Media' panel works as expected

         //Initiate our theme setup
         add_action( 'init', 'baltimore_theme_setup' );

         //Adding thumbnail image support to our 'Form' custom post type
         add_theme_support('post-thumbnails');
         set_post_thumbnail_size( 150, 194, true ); // Normal post
 thumbnails

         function baltimore_theme_setup() {
                 // This theme styles the visual editor with editor-
 style.css to match the theme style.
                 add_editor_style();

                 // This theme uses wp_nav_menu() in one location.
                 register_nav_menu( 'primary', __( 'Primary Menu',
 'baltimore' ) );

                 //Create the 'form-page' post type
                 register_post_type('form-page', 'supports' =>
 array('thumbnail');

                 //Create the 'type' taxonomy for the 'form-page' post type
                 register_taxonomy('form-page-type', 'form-page');
         }//end baltimore_setup



         //-------------------------------------------------


         //DOES NOT WORK - Breaks the 'Add Media' panel

         //DETAILS: The 'Add Media' panel for the post type 'form-page'
 opens, and allows you to upload media, but the uploaded media is not
 attached to the post. You can upload a media item, but it halts at
 'Crunching'. Going into the Media > Library does show the media item, but
 it's not attached to the post. Similarly, going into the post after
 uploaded, and going into the Gallery tab of 'Add Media', shows no media
 items.

         //Initiate our theme setup
         add_action( 'init', 'baltimore_theme_setup' );

         function baltimore_theme_setup() {
                 //Adding thumbnail image support to our 'Form' custom post
 type
                 add_theme_support('post-thumbnails');
                 set_post_thumbnail_size( 150, 194, true ); // Normal post
 thumbnails

                 // This theme styles the visual editor with editor-
 style.css to match the theme style.
                 add_editor_style();

                 // This theme uses wp_nav_menu() in one location.
                 register_nav_menu( 'primary', __( 'Primary Menu',
 'baltimore' ) );

                 //Create the 'form-page' post type
                 register_post_type('form-page', 'supports' =>
 array('thumbnail');

                 //Create the 'type' taxonomy for the 'form-page' post type
                 register_taxonomy('form-page-type', 'form-page');
         }//end baltimore_setup
