Are you sure your callback is being given a string?

From a quick look at
http://zeromq.github.com/pyzmq/api/generated/zmq.eventloop.zmqstream.html,
it says callback must take exactly one argument, which will be a list, as
returned by socket.recv_multipart() - i.e. not just a simple string.

No, my callback is given a protobuf serialized message. Exactly the same as
was sent in the first place.

To explain a bit more: I've got earth and heaven. Earth sends heartbeats
and heaven responds back. If no message has been received on either side
for more than two seconds both ends start another task while earth keeps
sending messages hoping for heaven to come back. The codes are as follows:

earth.py: http://pastebin.com/tvvSZeNR
heaven.py: http://pastebin.com/rtzCsuvg
link to errors: http://pastebin.com/jX4SFapt
compiled protobuf message encoder in python:

Do you understand any of this?
