Comment 2 for bug 1384919

So this is rather mysterious. pbr isn't in the habit of randomly assigning None to attributes of modules.

https://github.com/mitsuhiko/markupsafe/blob/master/markupsafe/_compat.py is the code in question, and pbr's absence certainly can't explain sys module attributes being bong.

Can I see the print output - I'm particularly interested in whether PY2 is assigned correctly, and what the content of builtins() is when those if blocks run.
