title: Devise (or OmniAuth) appending "#_" to URL after sign in
body: <p>I'm using Devise and OmniAuth (Facebook) in a Rails 3 app.  I just started noticing this behavior recently.</p>
  
  <p>When a user signs in, he is redirected to his dashboard, however, the characters "#_" are being appended to the url.  The only thing I can think of now is a conflict between the routes created by:</p>
  
  <pre><code>  resources :users
  </code></pre>
  
  <p>and</p>
  
  <pre><code>  # User Authentication
    devise_for :users,
           :singular =&gt; :user,
           :controllers =&gt; {:registrations =&gt; 'registrations'} do
      get 'logout' =&gt; 'devise/sessions#destroy'
    end
  </code></pre>
