title: Fatal error: Class 'Symfony\Component\Console\Input\ArgvInput' not found in app/console on line 16
body: <p>I got a working symfony app, today I decided to do a <code>composer update</code></p>
  
  <p>the result of the <code>composer update</code> can ben found here <a href="https://github.com/allan-simon/oauth2-symfony2-vagrant-fosuserbundle/commit/dfa25593f79c5595ca4759803ec1e998091c68b9">https://github.com/allan-simon/oauth2-symfony2-vagrant-fosuserbundle/commit/dfa25593f79c5595ca4759803ec1e998091c68b9</a>  (mostly change in minor version, note there's a change in version of symfony, but keeping it to 2.6 produce also the problems below)</p>
  
  <p>And now after the upgrade I got this error </p>
  
  <p>Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-update-cmd event terminated with an exception</p>
  
  <pre><code>[RuntimeException]

    .   
  </code></pre>
  
  <ul>
  <li>The content of the app/console has not changed</li>
  <li>I've tried deleting and recreating the bootstrap.cache no change</li>
  <li>In my vendor directory, I do have said <code>ArgvInput</code> class </li>
  </ul>
  
  <p>Any idea on what can the problem be ?</p>
