What client(s) are you using?

The only code path I can see to this error entails pipelining of 
synchronous commands on a channel, which the AMQP spec forbids.

Specifically, the error could occur when sending a basic.consume 
followed by a basic.cancel without waiting for the basic.consume_ok first.

Which is pretty much impossible in most clients unless there are 
multiple application threads operating on the same channel, which is 
usually a bad idea.
