issue with implicit-namespaces

I can run this without issue:

sphinx-apidoc -f --implicit-namespaces --no-toc --ext-todo --ext-intersphinx --ext-viewcode -o source/apidoc <excludes>

without issue

However when I run the same with better-apidoc like this:

better-apidoc -t './rst_template_dir' -f --implicit-namespaces --no-toc --ext-todo --ext-intersphinx --ext-viewcode -o source/apidoc <excludes>

I get the following:

Traceback (most recent call last):

I don't appear to get any error when not using --implicit-namespaces: for whatever that's worth.
