I'm in the process of upgrading a Rails 3.2 app to Rails 4.1. Whenever I try to start the console or server though, I come across this error:

Not really sure what's causing it and wondered if anyone has any advice. I tried this in irb and didn't encounter any problems (an error is raised as it should be):
irb(main):001:0> require 'active_support/core_ext/time/zones'
=> true
irb(main):002:0> Time.find_zone!('good')
ArgumentError: Invalid Timezone: f

Gemfile includes:
ruby "2.0.0"
gem "rails", "~> 4.1.0.beta1"
gem 'tzinfo-data'
Edit (some more info):
It seems as if the inclusion of the gem 'tzinfo-data' might be messing something up? When the gem is in the gemfile, in seems as if 'tzinfo' isn't ever getting required during the RailsApp::Application.initialize! call in environment.rb. However, when the gem is removed, the require is happening.
Requiring the tzinfo gem before initializing the app in environment.rb fixes the issue for me. Doesn't really explain everything, but seems to work
# adding this fixes the issue
require 'tzinfo'
# Initialize the rails application
RailsApp::Application.initialize!
Edit: Seems this was a problem with Rails: https://github.com/rails/rails/issues/13553
This worked for me:
gem uninstall tzinfo
#select 'All versions'
gem install tzinfo
rails c
