I am getting these kind of messages in appengine log while it
seemingly works fine (ie hub notifications received & processed
properly) :
Cannot operate on different entity groups in a transaction:
(kind=u'FeedRecord',
name=u'hash_a73467635489ca5500d93b726451a42839b1dffc') and
(kind=u'FeedRecord',
name=u'hash_a6b9be9560fd1f42034a028eb3ac0d5932603ec1').
