Probably related to #890 and not sure if to #1070

When compiling the last stable, Babel exits with this error message:

babel.core.UnknownLocaleError: unknown locale 'ia'

Workaround from ​http://pastebin.com/Cc37uigc (this links expires in 30 days):

This part of the instalation process of mediagoblin on debian jessie: ​http://mediagoblin.readthedocs.org/en/stable/siteadmin/deploying.html#install-mediagoblin-and-virtualenv Fails for me at "make" with the following error message:

babel.core.UnknownLocaleError: unknown locale 'ia'

So I had to:

sudo apt-get install python-babel-localedata

# And then:

DIR_ORIGIN="/usr/share/python-babel-localedata/localedata/"
DIR_DESTINATION="/srv/mediagoblin.example.org/mediagoblin/lib/python2.7/site-packages/Babel-2.2.0-py2.7.egg/babel/locale-data/"
sudo ln ${DIR_ORIGIN}ia.dat ${DIR_DESTINATION}/
sudo chown mediagoblin:www-data ${DIR_DESTINATION}/ia.dat

Now it has compiled sucessfully.

Currently the resized images are quite heavily artefacted. It would be nice if the user (or possibly the server owner) could set custom compression levels to trade off size/quality.
