While browsing for MM options through admin_menu module I found that 'configuration' link leads to admin/build/media_mover.
Also landing on the admin/build/media_mover also returned a warning saying
"
warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'media_mover_ui_landing_page' was given in /var/www/drupal/includes/menu.inc on line 349.
"
So I commented out the code leading to 'admin/build_media_mover' until its added.
attaching a patch...

Instead of commenting it out change:

 $items['admin/build/media_mover/default'] = array(
    'title' => 'Configurations',
    'page callback' => 'media_mover_ui_landing_page',
    'type' => MENU_DEFAULT_LOCAL_TASK,
    'weight' => -3,
  );

to:

  // Render landing page as the default tab
  $items['admin/build/media_mover/default'] = array(
    'title' => 'Configurations',
    'page callback' => 'media_mover_ui_configurations_view',
    'type' => MENU_DEFAULT_LOCAL_TASK,
    'weight' => -3,
  );

Fixed the blank page problem for me.
