network_shape middleware crashes Muxy

[gregopet]

I'm trying to use Muxy to test a TCP protocol and it crashes as soon as I turn on the network_shape middleware (tried copying the default settings).

There is nothing in the program output that would point to the problem, this is what I get before the program exits:

I'm running Muxy 0.05 on an OpenSuse Linux with kernel version 3.12. I downloaded the binary release from Github and also tried the 0.06 pre-release, with the same result.

One more thing I've tried: I used the docker image github.com/mefellows/docker-muxy and it fails in the same way.

Also tried on a Linux with a less ancient kernel & the docker image, an Ubuntu Xenial Xerus with the 4.4.0 kernel, and the result was the same.

Hi @gregopet, apologies I didn't see this. Let me take a look!

Please see #23 to track this.
