As part of a datastore query, I get back entities that have a KeyProperty. When trying to call a .id() on the KeyProperty, I get the following TypeError thrown:

TypeError: 'long' object is not callable

Upon examining the particular key, I see this (obfuscated):

<Key[{'kind': u'xxxx', 'id': 1234567890L}], project=xxxx>

Not sure exactly where the TypeError is being thrown, but it looks like the 'id' is being interpreted as a long somehow, when it's actually a standard integer.

I've had to workaround this by doing the following:
Key._path[0].get('id')
