Lately we've had a couple of users complain that make fails because the python2 install requires mock, and latest mock now requires a more recent version of setuptools than their distribution provides.

mock: mock requires setuptools>=17.1

Can we pin mock at a lower version to prevent this issue?

Looks like the pdf plugin can't handle PDF files.

1. Setup production environment:
2. Enable PDF support: ​https://mediagoblin.readthedocs.io/en/latest/siteadmin/media-types.html#pdf-and-document

sudo apt-get install -y poppler-utils echo "mediagoblin.media_types.pdf" >> mediagoblin_local.ini git submodule init && git submodule update ./bin/gmg dbupdate sudo service mediagoblin-paster restart

3. try to upload attached sample PDF
