Applied Educational Systems

I get this error on local machines (OSX and Ubunto on Vagrant) and also on my hudson CI server. Sometimes the tests work fine and other times they fail.

FYI: I was able to fix the problem by changing the validate scripts setting. My application is Rails3 with prototype.js Capybara.register_driver :akephalos do |app| Capybara::Driver::Akephalos.new(app, :validate_scripts => false) end
