title: $language->language get the de default language not current language [Drupal 7]
body: <p>I have a custom module, and on its controller, when I try to get the current interface language. I get the default language 'en'.</p>
  
  <p>Someone can tell me why</p>
  
  <pre><code>&lt;?php
      function module_controller_my_function(){ 
          global $language;
          var_dump($language-&gt;language);
      }
  ?&gt;
  </code></pre>
  
  <p>it give the default language instead the current interface language</p>
