title: Symfony 1.4 i18n helper in action
body: <p>I have problem with using I18n _<em>() in Symfony 1.4 action.
  In component where I call _</em>('test',null,'translation') I get 'abcd' but when I call it in action I get 'test'. This indicate that it is not the problem with xliff file. </p>
  
  <p>In settings.yml there is i18n on</p>
  
  <pre><code>all:
    .actions:
      error_404_module:       errors   # To be called when a 404 error is raised
      error_404_action:       error404  # Or when the requested URL doesn't match any route
  #
      login_module:           default   # To be called when a non-authenticated user
      login_action:           login     # Tries to access a secure page
  #
      secure_module:          default   # To be called when a user doesn't have
      secure_action:          secure    # The credentials required for an action
  #
  #    module_disabled_module: default   # To be called when a user requests 
  #    module_disabled_action: disabled  # A module disabled in the module.yml
  #
    .settings:
  
       i18n:                   on  
  </code></pre>
  
  <p>The problem not even resolve adding to the action
  sfContext::getInstance()->getConfiguration()->loadHelpers(array('I18N'));</p>
