I haven't read AMQP 0.8 spec (which is what amqp gem before 0.8.0.RCs
implements) in a while but I cannot think of a case when the header may be
missing. My only suggestion is to not rely on "logging" of various clients
because they use different frame class names, framing strategies and so on.
Use Wireshark, it will tell you what is really going up and down the wire.
And, maybe upgrade to RabbitMQ 2.5.1 that still supports AMQP 0.8 as well as
AMQP 0.9.1.
