title: Django redirect with kwargs not working
body: <p>I have seen similar questions, this is not a duplicate. I have a simple redirect that recieves kwargs that is not working and I don't know why. The <a href="https://docs.djangoproject.com/es/1.9/topics/http/shortcuts/#django.shortcuts.redirect" rel="nofollow">docs</a> give this example:</p>
  
  <pre><code>def my_view(request):
      ...
      return redirect('some-view-name', foo='bar')
  </code></pre>
  
  <p>And it is exactly what I'm doing:</p>
  
  <pre><code>...
  ...
  return redirect('perfiles:despues_contacto', razon_contacto='donacion', correo_contacto='thrall@gmail.com')
  </code></pre>
  
  <p>The url pattern looks like this:</p>
  
  <pre><code>url(r'^gracias_por_contactarnos/(?P&lt;razon_contacto&gt;[-\w]+)/(?P&lt;correo_contacto&gt;[-\w]+)/$',
          views.DespuesContacto.as_view(), name="despues_contacto"),
  </code></pre>
  
  <p>?¿ What am I missing? maybe it is something obvious ... but my eyes are tired of trying to find the error. Is it the regex?</p>
