title: NoReverseMatch at /rosetta/. Reverse for 'rosetta-file-list' not found
body: <p>I want to add rosetta to my project and use it. </p>
  
  <p>First I installed it using pip -> 'pip install django-rosetta'</p>
  
  <p>Then I added it to my INSTALLED_APPS</p>
  
  <p>After that, I added the rosetta url to my project urls:</p>
  
  <pre><code>url(r'^rosetta/', include(('rosetta.urls', 'rosetta'), namespace='rosetta')),
  </code></pre>
  
  <p>But when I run the project and go to "<a href="http://127.0.0.1:8000/rosetta/" rel="nofollow noreferrer">http://127.0.0.1:8000/rosetta/</a>", it send me back this error:</p>
  
  <blockquote>
    <p>NoReverseMatch at /rosetta/</p>
    
    <p>Reverse for 'rosetta-file-list' not found. 'rosetta-file-list' is not a valid view function or pattern name.</p>
  </blockquote>
  
  <p>I have no idea where the problem is. Can anyone help me with this?</p>
  
  <p>Thanks in advance.</p>
