 In Codex the $src parameter in ''wp_register_script( $handle, $src, $deps,
 $ver, $in_footer )'' is required but is allowed to be empty.

 This makes it easy to make a plugin/theme that breaks other plugins.

 Some themes have this code loaded in init-hook:
 {{{
 if (!is_admin()) {
         wp_deregister_script('jquery');
 // De-Register jQuery
         wp_register_script('jquery', '', '', '', true);
 // It's already in the Header
 }
 }}}

 If a plugin that uses jQuery is used on the login page, it'll be broken.
 And you can't check if the script was correctly registered or not:
 {{{
     //This will return true even though $src was empty.
     if(wp_script_is('jquery', 'registered'))
 }}}
