Long time no chat.  Welcome back.

I agree with your patch, and analysis.  

The packet.py is very new, never been in a released version.  It is part
of the move to pure python, so not well tested yet.

Patch applied to git head.  Please test.

James did the new pure python.  I'll ask his opinion.

The gpsd python 2 support is going to be very hard to maintain, but
I'll try as long as I can, and get good help like yours.
