The Problem

If you're unfamiliar with the issue, there is an intermittent failure when running Capybara tests on any machine (spec/requests/ or features/):

undefined method `db_charmer_connection_name' for #<ActiveRecord::ConnectionAdapters::Mysql2Adapter:0x00000009f16ec8>
/var/lib/jenkins/.rvm/gems/ruby-1.9.3-p0/gems/db-charmer-1.7.0/lib/db_charmer/active_record/class_attributes.rb:85:in `db_charmer_remapped_connection'
