Turbolinks related error when using comfortable_mexican_sofa

This is the error generated whenever I try to do a simple page reload:

From the Gemfile.lock:

comfortable_mexican_sofa (1.8.5)
turbolinks (5.2.0)
  turbolinks-source (~> 5.2)
turbolinks-source (5.2.0)

DEPENDENCIES
  comfortable_mexican_sofa (~> 1.8, >= 1.8.5)
  turbolinks (~> 5.2.0)

Rails 3.2.

What could be causing this?

It seems the issue was the version of Turbolinks I was using.

Turbolinks 5 doesn't seem to work with Rails 3.2.

So once I did this in my Gemfile:

gem 'turbolinks', '~> 2.5', '>= 2.5.3'

And then did a bundle install and/or bundle update it works like a charm now.
