Twitter gem & Rails 3 - TypeError: can't convert Pathname into String

I'm trying to use the twitter gem in a rails 3 app but keep getting the following error:

TypeError: can't convert Pathname into String

Here's the code I'm trying to run:

class Tweet < ActiveRecord::Base
  def self.test_tweet
    Twitter.user_timeline("sferik").first.text
  end
end

Here's the full error message:

TypeError: can't convert Pathname into String

I get this error even when running the same code from the console:

Twitter.user_timeline("sferik").first.text

I created a blank test app with the same version of rails and the twitter gem and it runs no problem so I'm not sure what the problem is.

As I had this working before in the app I went back through my commits until I could find a point were it was working and what I did to break it.

So in case anyone happens to be in the same position what I had added was a fix_ssl.rb file in config/initializers which was to address a previous SSL connection issue. Removing this file allowed the Twitter gem to work correctly again.

config/initializers/fix_ssl.rb

require 'open-uri'
require 'net/https'

module Net
   class HTTP
    alias_method :original_use_ssl=, :use_ssl=

    def use_ssl=(flag)
      self.ca_file = Rails.root.join('lib/ca-bundle.crt')
      self.verify_mode = OpenSSL::SSL::VERIFY_PEER
      self.original_use_ssl = flag
    end
  end

end
