Hi Kevin,

To set the Content-Length header, you have to have the whole response 
in memory. And since the beginning my aim has been to have rpclib work 
without having the whole message in memory in order to have the ability 
to return HUGE responses. (see the roadmap document) So I've 
intentionally suppressed the Content-Length header from responses. But I 
never thought this would have side effects. So here's a quick patch for 
that: 
https://github.com/plq/rpclib/commit/7092617b74bd6b3a2d57fd9833336b851208a672

Does it work for you?

You're right, There's been a long time since I touched the mtom code. I 
doubt it works at all.
