    It's expected that gtk_widget_get_root() will return NULL if the widget
    tree does not contain a root widget. I don't know what that means or why
    it happens, but it's true in gnome-control-center's network panel when
    displaying the OpenVPN configuration dialog. We need to handle it.
    Fixes #6056
