GeocellManager.proximityFetch throws exception in AppEngine

[GoogleCodeExporter]

What steps will reproduce the problem?

private static final Key SMALLEST_KEY = 
KeyFactory.createKey(MyLocationCapable.class.getSimpleName(), 1);
private static final GeocellQuery GEOCELL_QUERY = new GeocellQuery("key >= 
idParam", "com.google.appengine.api.datastore.Key idParam", 
Lists.<Object>newArrayList(SMALLEST_KEY));

    Point center = new Point(latitude, longitude);
    PersistenceManager pm = PMF.instance().getPersistenceManager();
    return GeocellManager.proximityFetch(center, 4, 100, MyLocationCapable.class, GEOCELL_QUERY, pm);

What is the expected output? What do you see instead?
expected to get back some MyLocationCapables.  Instead I get a stack trace:

What version of the product are you using? On what operating system?

This is deployed to appengine.  Using geocell-0.0.3-SNAPSHOT.jar  that I 
downloaded last night (10/30/2010)
