 To replicate, in the Twenty Eleven theme I added this right after
 add_custom_background();

 {{{
 define( 'BACKGROUND_IMAGE',
 'http://s.wordpress.org/style/images/wp3-logo.png' );
 }}}

 Viewing the site now shows the WordPress logo tiled across the background.

 If you go to Appearance > Background, the Preview doesn't display the
 background image. If you upload another image, then click the "Restore
 Original Image" button, the preview stays empty but the actual background
 of the site displays the default image.

 I've tried it with an absolute URL like above, absolute URL to image in
 the current WP install, and using get_bloginfo('url') or
 get_bloginfo('stylesheet_directory') to generate the proper URL.

 When you View > Source of the admin page, this is what's showing up in the
 preview box:


 {{{
 <div id="custom-background-image" style=" background-image: url('');
 background-repeat: repeat; background-position: top left"><img class
 ="custom-background-image" src="" style="visibility:hidden;" alt="" /><br
 />
 <img class="custom-background-image" src="" style="visibility:hidden;"
 alt="" />
 </div>

 }}}
