It sucks when the Googlebot catches you with your pants down, as
apparently was the case with Last.fm recently. Don't they have some
kind of pre-deployment test suite? That's a pretty low-level error,
apparently from the PHP Smarty templating engine. Of course, I'm sure
Google hits them pretty frequently, so it will be fixed soon. But, if
your site is uber-low traffic, that sinopsis could be up there for
weeks.
