title: saved instance bundle is null in onCreateView for DialogFragment
body: <p>I am saving a key value pair before displaying the warning dialog. However the <code>onCreateDialog()</code> for the dialog is called with a null bundle. Is there something extra I need to do to pass the bundle to the dialog?</p>
  
  <pre><code>MyDialogFragment testFrag= new MyDialogFragment();
  Bundle args = new Bundle();
  args.putString("car-type", "Audi");
  testFrag.setArguments(args);
  testFrag.show(getFragmentManager(), "info");
  </code></pre>
