So the STOMP protocol, http://stomp.codehaus.org/Protocol, says this on the
subject:

  "It is recommended that SEND frames include a content-length header which
   is a byte count for the length of the message body. If a content-length
   header is included, this number of bytes should be read, regardless of
   whether or not there are null characters in the body. The frame still needs
   to be terminated with a null byte and if a content-length is not specified,
   the first null byte encountered signals the end of the frame."

(MESSAGE frames have a very similar paragraph in their description.)

The RabbitMQ STOMP server plugin pays attention to this content-length header.
It also *always* supplies a content-length header on MESSAGE whenever the
message body is non-empty.

Hey this is excellent news! Will you be able to send us a patch?

I think you might need our key for that. (Which clearly isn't an option :-) ) I
suspect you will have to recompile the DLLs you have that depend on the
RabbitMQ client to have less strict dependencies. I'm afraid I'm not an expert
on the vagaries of .NET linking, though :-/
