What is the current behavior?

When you generate a brand new padrino app and, then, generate an admin section, it seems the admin section fails to find the locale.

To reproduce:

# variables
project=test

# create a sample app
padrino g project -d sequel -a sqlite -s jquery -e slim "${project}"
cd "${project}"

# enable thin
sed -ri "s@^# gem 'thin'@gem 'thin'@" Gemfile

# bundler
bundle config set --local path 'vendor/bundle'
bundle install
bundle binstubs --all

# install bootstrap
bundle exec padrino g plugin bootstrap

# generate Admin section
bundle exec padrino g admin

bundle install
padrino rake db:migrate
padrino rake db:seed

# run padrino
padrino start

# open admin
firefox http://127.0.0.1:3000/admin/

What is the expected behavior?

The admin page should show up and ask you for your credentials.

Which versions of Ruby, Padrino, Sinatra, Rack, OS are you using? Did this work in previous versions?
