When trying to request an access token using the /oauth/access_token route it 500's with the following error in the logs:

File '/srv/audio-video-new.gnu.org/mediagoblin/mediagoblin/plugins/oauth/views.py', line 224 in access_token
  (token.expires - datetime.now()).total_seconds()))}
AttributeError: 'datetime.timedelta' object has no attribute 'total_seconds'

Hi,

I checked out mediagoblin from source and wanted to start testing. However before that I'd like to know who wrote the code. Therefor I'd be very nice, if you could sign your git tags with git tag -s (man git-tag).

Thank you!

To reproduce:

• Go to a media page
• Click "Add media to collection"
• On the resulting page, don't select a collection from the dropdown so it stays on "-- Select --"
• Click "Add"
• MediaGoblin crashes with this message: "AttributeError: 'NoneType' object has no attribute 'id'"

Possible options:

• Return an error when no collection is specified
• Remove the "-- Select --" option from the dropdown (thereby automatically selecting a certain collection - maybe the default "Favorites" collection we talked about?)
