Ian, This is by design and one of my peeves at the moment. A number of the datastore properties will throw an exception when given None values, so it makes them useless for storing optional properties. I think I ran into the same problem with LinkProperty and EmailProperty. The general solution is to just use a StringProperty. You could use a "None" marker like "http://nolink"; or "not specified" depending on validation of the property, but I find this less appealing.
