Comment 8 for bug 1655049

The actual source of the issue seems to be that netaddr indexes a file that it doesn't own (from ieee-data package), and then assumes that it won't change underneath it (either because of an ieee-data update, or a netaddr update in the case of a running process), which results in various exceptions and other errors from the code. I believe that a fresh bug is being filed against python-netaddr on the issue.
