This is happening because there was a [new version of `database_cleaner`](http://rubygems.org/gems/database_cleaner) released. It's this commit in this new version that breaks it: https://github.com/bmabey/database_cleaner/commit/6a0104382647e5c06578aeac586c0333c8944492.

This is not the first time that this is happened. I think we should explicitly freeze the gem dependencies inside the Gemfile to prevent this kind of obscure break from happening again.
