I have a similar problem:

# Sphinx version: 1.6.1
# Python version: 2.7.13 (CPython)
# Docutils version: 0.13.1 release
# Jinja2 version: 2.9.6
...
  File ".../lib/python2.7/site-packages/sphinx/themes/basic/../basic/layout.html", line 108, in template
    {%- for css in css_files %}
TypeError: 'NoneType' object is not iterable

Is the problem that nothing sets css_files?

tk0miya · 2017-05-17T14:42:56Z

Fixed at 62614af. Could you check this please if possible?

ulsa · 2017-05-17T15:14:26Z

One workaround is to install sphinx==1.5.6.

zapme · 2017-05-17T15:17:19Z

Checked, works for me.

pcav · 2017-05-17T17:00:30Z

Confirmed. Thanks.

theacodes · 2017-05-20T00:00:40Z

Any idea when this will be released? It's currently breaking the build for packaging.python.org. (I'm going to pin to 1.5.6 in the meantime)

See: sphinx-doc/sphinx#3754

tk0miya · 2017-05-22T15:14:32Z

I'm very sorry. Now I don't have enough time for new release.
It might be at this weekend.
