Are you saying that you expect this to be a onebox but isn’t?
It tries to onebox it but fails with this exception:
ActionView::Template::Error: odd number of arguments for Hash

There was an error with parsing the query parameters in the onebox gem. I fixed it in the gem but unfortunately there’s still an error with that URL, since it doesn’t seem to have the
ll parameter for the location that the Google Maps oneboxer requires.
