This problem is similar to issue 213 in that they are both caused by the 
GadgetLinker
template not including a full blown hosted.html for hosted mode.

Still having it with GWT 1.7 and gwt-gadgets-1.0.3.

The same exact exception under Windows XP.

I wrote a simple workaround this way:

    static {
        disableStats();
    }

    private static native void disableStats() /*-{
        $wnd.$stats = null;
    }-*/;

but I would like to know if I did something bad or if there are still issues 
about 
RPC under GWT and Google Gadgets.
