Looks like a bug in the client to me - you're setting prefetch_count,
which we do implement, but the server's receiving a non-zero value for
prefetch_size (which we don't implement).
You could try explicitly setting prefetch_size to 0 as well, and see if
that helps, but unless there's something funny going on elsewhere, it
smells like a bug in txamqp to me (though I've not checked the code).
