I was able to reproduce the bug fairly easily on Ubuntu 16.0.4 using Python 3.5.2 as shown below. reproducing the bug

I then ran a regular IP().show() just for a comparison. an interesting observation

It was here that I observed that the flags field was empty or not being set. flags not set

On a whim I tried fuzz(IP()).show() again, though this time I manually set the flags instead of letting them be randomly set by fuzz. The result was that this time the function succeeded in printing the packet as shown below.

works fine when flags are set works fine when flags are set second example
