Peter,

I'm not seeing this behavior.  I created a new Fedora26 virtual machine
for isolation purposes.  On that system I downloaded and compiled the
master branch (at 648a40d5), and started mythbackend under my userid. 
I then created another user, started a shell as that other user, and
ran mythfrontend.  It seems to find the backend without any problem and
starts right up.  I must be doing something wrong, because after
setting a pin and deleting the ~/.mythtv directory for the frontend, 
the frontend will still connect without any problem and without asking
for a pin.  I see this same behavior when running either 708baf28
(which works for you) or 648a40d5 (which fails for you). 

I will keep playing with this and see if I can recreate the correct
behavior with 708baf28, and then the bad behavior of 648a40d5.

I have uploaded logs to pastebin.  If you could give them a quick look
and see if you can spot what I'm doing wrong, I would appreciate it.
