Possible error in latest git pull

Just did a git pull on pgadmin4 and on attempt to start the web
interface I have a problem. App seems to start correctly and invites me
to open my browser, but on attempt to log in I get a rotating wheel and
this in the console. Quite possibly my error, on openSUSE Leap 42.1
fully patched:

 > python pgAdmin4.py
Starting pgAdmin 4. Please navigate to http://localhost:5050 in your
browser.
