It seems a bit odd that a producer is declaring a queue at all. Information
flow in AMQP is asymmetric. Producers send messages to exchanges, which route
on to queues, which deliver to consumers. A producer doesn't need to declare or
manipulate queues: if one piece of code both publishes to an exchange and reads
off a queue, it's performing in both the producer and the consumer roles.

Not sure if this sheds any light on your issue of course :-)
