Running python setup.py develop on Ubuntu Natty doesn't work. PIL
doesn't get compiled with jpeg or png support. This happens with
both the virtualenv and buildout instructions.

Doing a Google search leads to the following interesting urls:

This is a big deal because it means people using Ubuntu Natty can't
run GNU MediaGoblin.

Currently you can try to upload a html file.

What happens currebtly? It sticks in the queue, because celery goes
crazy on it.
The good news: It does not end up in a public place.

What should NEVER, ever happen: The file being put in a public
place. It's the best XSS attack to come up with.

Rating this high, because this needs to be right for security
reasons.

We haven't explained now what kind of patches we want or how to
push a branch for us to merge in the docs. Well, at least we
haven't explained the patch part well. We should basically give an
example tutorial session on how to submit a proper patch.
