How are you observing the queue message counts? Via 'rabbitmqctl 
list_queues'? If so, what does the breakdown into messages_ready, 
messages_unacknowledged and messages_uncommited show?

That's very odd. Can you post some code to reproduce this behaviour? 
Also, it would safe time if you repeated the tests on the 1.7.0 client 
and server.
