Getting NoneType css_files or theme_css_files after Sphinx Upgrade #158
Description
I upgraded my Sphinx (to 1.6.1) to install another package this morning, and now my build using sphinx_bootstrap_theme (version 0.4.14) gives me the following error:
Exception occurred:
File "/usr/local/lib/python2.7/dist-packages/sphinx_bootstrap_theme/bootstrap/layout.html", line 40, in top-level template code
{% set css_files = css_files + theme_css_files + bootswatch_css_custom %}
TypeError: unsupported operand type(s) for +: 'NoneType' and 'list'
The full traceback has been saved in /tmp/sphinx-err-Jz7JLa.log, if you want to report the issue to the developers.Sphinx works with html_theme = 'alabaster' instead of sphinx-bootstrap, so I believe it's in sphinx-bootstrap-theme. My relevant configuration lines are:
html_theme = 'bootstrap'
html_theme_path = sphinx_bootstrap_theme.get_html_theme_path()
html_theme_options = {
# Tab name for entire site. (Default: "Site")
