You have to either update therubyracer or downgrade the twitter-bootstrap-rails gem down to version 2.1.7 which is the last known version that didn't have this issue.
Run either bundle update to update your gems or in your Gemfile make your twitter-bootstrap-rails gem look like this:
gem 'twitter-bootstrap-rails', '2.1.7'
Take a look at this issue:

This issue started happening on versions after 2.1.7 on twitter-bootstrap-rails.
