Did you use the spec files that were shipped with txAMQP or the official 
ones[1]?

Note that there are interoperability issues between the Qpid Python libraries 
and RabbitMQ. From http://www.rabbitmq.com/interoperability.html:

"Note that the 0-8 spec file that comes with the test suite is different from 
the official spec."

What's in the rabbit.log file? When I wrote that example, I noticed that 
RabbitMQ couldn't decode the basic.consume frame:

connection <0.202.0> (running), channel 1 - error:
{amqp,frame_error,
      "cannot decode 
<<0,0,12,116,101,115,116,45,113,117,101,117,101,45,49,0,0,0,0,0,0>>",
      'basic.consume'}

however, using the official spec fixed the issue.

Cheers.
