I installed the Drupal Big Stream theme (7.x 1.0) on a LAMP stack recently (after I bought it) and I did setup the first pages.

Bundled with is is the Drupal MD FullScreen Slider 7.x-2.2 module. The server runs PHP 5.4.41-0+deb7u1, Apache2 with mod_php and as far as I can see it there are no errors but 1:

1.) When I go Structure -> MD FullScreen sliders the page just stops. The screen remains white and the Dev console of the browser shows a 500.

2.) I check the respective logs of the server:

In the Apache error log I see:

PHP Fatal error:  Call to undefined function media_browser_js() in /var/www6/sites/all/modules/custom/md_fullscreen_slider/inc/md_fullscreen_slider.utils.inc on line 442

3.) I check for the code
/**
 * Callback function to include mediaBrowser.js
 */
function _md_fullscreen_slider_include_media_browser_js() {
  static $included;
  if ($included) {
    return;
  }
  $included = TRUE;
  module_load_include('inc', 'media', 'includes/media.browser');
  $javascript = media_browser_js(); // here is the problem
  foreach ($javascript as $key => $definitions) {
    foreach ($definitions as $definition) {
      $function = 'drupal_add_' . $key;
      call_user_func_array($function, $definition);
    }
  }
  // Add wysiwyg-specific settings.
  $settings = array('wysiwyg_allowed_attributes' => variable_get('media__wysiwyg_allowed_attributes', array('height', 'width', 'hspace', 'vspace', 'border', 'align', 'style', 'class', 'id', 'usemap', 'data-picture-group', 'data-picture-align')));
  drupal_add_js(array('media' => $settings), 'setting');
}

Apparently there is an issue with this... can someone help me with this? It is part of the fullscreen slider module. media_browser_js() is probably a deprecated function. I have to research this... however I guess that bug somehow got into the release pipeline for me.
