Kamene causing python3 segmentation fault

I have a basic python3 script for running a ping sweep using kamene with two main issues. I'm not sure if they are related so I'll add them both in the same post.

Where in here is the main issue and what have I done wrong?

First issue... When I import IP and ICMP from kamena.all I have an error as below...

No name 'IP' in module 'kamene.all'pylint(no-name-in-module)

No name 'ICMP' in module 'kamene.all'pylint(no-name-in-module)

Second issue...

When I run the program, I get an IPv6 error and then a segmentation fault with a warning from OSX to say that python has stopped.

python3 pingsweep.py 
WARNING: No route found for IPv6 destination :: (no default route?). This affects only IPv6
Segmentation fault: 11

This is my script code...

from kamene.all import sr1,IP,ICMP

for ip in range(1, 8):
  packet = IP(dst="192.168.0." + str(ip), ttl=20) / ICMP()
  reply = sr1(packet, timeout=2)

  if not (reply is None):
    print(reply.dst)

I have installed kamene with...

pip3 install kamene

Lastly, the crash report from OSX...

I cannot reproduce your issues with Scapy, so I'll assume that's only related to Kamene (I have edited your question to reflect that).

You can either try using the "real" Scapy (https://github.com/secdev/scapy), or report this issue to the Kamene project.
