Thumbnails for some images, like
`http://mg.wandborg.se/u/abner/m/fdfs/ <http://mg.wandborg.se/u/abner/m/fdfs/>`_
have a tendency to look ugly when transformed to JPEG,
`http://i.imgur.com/QM0sw.png <http://i.imgur.com/QM0sw.png>`_.

One way to remedy this would to save PNG image thumbnails as PNGs.

mongokit supports accessing fields not only as ``doc['field']`` but
also as ``doc.field``.


-  This might look more pythonic.
-  This will ease a possible transition to sqlalchemy (as this it
   the sqlalchemy way)
-  Docs:
   http://namlook.github.com/mongokit/tutorial.html#dot-notation Main
   questions:
-  Switch it on now or in the sql-migration branch?
-  If switching it on now, should all accesses be converted to the
   new syntax?

I edited my profile info on mediagoblin.com. I put something in the
"bio" field but left the "website" field empty.

Result: neither of these are shown on my profile page
(`http://mediagoblin.com/u/schendje/ <http://mediagoblin.com/u/schendje/>`_).
Instead, it reverts to the "Here's a spot to tell others about
yourself." state.
What should happen: only the bio info should appear.

If you only enter your website, but no bio, it works correctly and
shows the website info on your profile.
