title: Class 'Imagine\\Imagick\\Imagine' not found Symfony 2.1
body: <p>I want to integrate the <a href="https://github.com/liip/LiipImagineBundle/" rel="nofollow">LiipImageBundle</a> in my Symfony 2.1 project.</p>
  
  <p>I installed the bundle and the <code>imagine/Imagine v.0.4.0</code> bundle via composer.
  It's seems to work fine, except, that the modified images are not saved.</p>
  
  <p>The <code>error.log</code> states:</p>
  
  <p><code>PHP Fatal error:  Class 'Imagine\\Imagick\\Imagine' not found in /var/www/app/cache/prod/appProdProjectContainer.php on line 365</code></p>
  
  <p>This line in <code>appProdProjectContainer.php</code> states:</p>
  
  <pre><code>protected function getLiipImagineService()
  {
      return $this-&gt;services['liip_imagine'] = new \Imagine\Imagick\Imagine();
  }
  </code></pre>
  
  <p>I have no idea if this is correct or not. Have you guys any idea why PHP cannot find the class?</p>
