Since there is no section in the bugtracker for [community] packages, and the maintainer was not in #archlinux, it seemed that this was the best place for this.

python-setuptools 1:19.3-1 breaks youtube-dl.

Steps to reproduce: Update python-setuptools to 1:19.3-1 and use youtube-dl.

Output:

Traceback (most recent call last): File "/usr/bin/youtube-dl", line 5, in <module> from pkg_resources import load_entry_point File "/usr/lib/python3.5/site-packages/pkg_resources/__init__.py", line 48, in <module> from pkg_resources.extern import six File "/usr/lib/python3.5/site-packages/pkg_resources/extern/__init__.py", line 60, in load_module "distribution.".format(**locals()) ImportError: The 'six' package is required; normally this is bundled with this package so if you get this warning, consult the packager of your distribution.

Workaround: Downgrade python-setuptools to version 1:19.2-1.

I am not familiar enough with youtube-dl to propose a solution, but it would seem a simple rebuild would be sufficient.
