This is an error in PyProtocols (I guess it's just a bug inside the C
code of PyProtocols), I also get that here. The workaround is to install
PyProtocols without those speedups so that it's just a pure Python
module. You can do that by passing a special option to the setup script
(I think it's called --without-speedups or something like that. Have a
look into the install docs).

My longer term plan is to get rid of PyProtocols at some time, but
that's not a quick task so don't hold your breath.

Cheers,
