Hi James, this comes from UnprocessedMessage_0_8 where _exchange seems not to be initialized - no idea why.
Anyway is there some reason to use AMQP 0.8 or BURL syntax (deprecated in favour of address strings)? It is probable the apparently bug is not present when using either address strings or higher AMQP protocol version (currently in qpid client, 0.10).
