pyroute2 0.4.21 / py3.5.2 / ubuntu 16.04

upgraded to git master and haven't reproduced yet, but behavior is somewhat stateful and I don't have a concise test case asof yet.

cheers!

issue is confirmed on

pyroute2==0.4.18.post92

installed via

sudo pip install --upgrade git+https://github.com/svinota/pyroute2.git#master

I still don't have a nice test case as the issue doesn't present itself reliably.

Should be fixed now, thanks for the report!
