Some asserts has been done in Frame#4.

  1244 static void

  1246 {
  1247         GdmDisplay *display;

  1252 
  1253         g_assert (display->priv->status == GDM_DISPLAY_FINISHED ||
  1254                   display->priv->status == GDM_DISPLAY_FAILED);

  1258 
  1259         G_OBJECT_CLASS (gdm_display_parent_class)->dispose (object);

An allocation should previously be released, but dit not be released.
