On further though I really think you are going about this the wrong way.
You haven;'t said if you using ndb or db, if you are using ndb you should
be providing a function to validator argument that will co-erce the data
for you.
Alternately subclass the Property to provide the functionality you want and
not override __setattr__ which as you have found out could/will cause
problems
with new releases of the appengine runtime, as you are not using the public
api for models/properties.
