title: Can't access users page in wagtail admin
body: <p>I have a problem with my wagtail admin interface. In my urls.py I put it like that:</p>
  
  <pre><code>url(r'^cms-admin/', include(wagtailadmin_urls)),
  url(r'^cms-search/', include(wagtailsearch_frontend_urls)),
  url(r'^cms-documents/', include(wagtaildocs_urls)),   
  url(r'', include(wagtail_urls)),
  </code></pre>
  
  <p>All links except the one to users (/cms-admin/users/) work fine. When I go to /cms-admin/users/ I get the following error: </p>
  
  <pre><code>NoReverseMatch at /cms-admin/users/
  Reverse for 'wagtailusers_edit' with arguments '(-1L,)' and keyword arguments '{}' not found. 1 pattern(s) tried: ['cms-admin/users/(\\d+)/$']
  </code></pre>
  
  <p>Further down I see that Django tries to render a template and has problems with that line: </p>
  
  <pre><code> &lt;a href="{% url 'wagtailusers_edit' user.id %}"&gt;{{ user.get_full_name|default:user.username }}&lt;/a&gt;
  </code></pre>
  
  <p>Does anyone have an idea what I am doing wrong?</p>
  
  <p>Thanks
  Magda</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>OK, I found out myself - the problem is that I have an anonymous user with the ID -1 and wagtail uses that pattern: <code>['cms-admin/users/(\\d+)/$']</code>. Still I don't know how to solve this.</p>
