bundle error running test on a simple app

I have created a new app with --edge and created a scaffold and migrated the database. When I execute 'rake test' I get this error:

.bundle/gems/bundler-0.9.5/lib/bundler/resolver.rb:161:in `resolve': Could not find gem 'rails (>= 0, runtime)' in git://github.com/rails/rails.git (at master). (Bundler::GemNotFound) Source does not contain any versions of 'rails (>= 0, runtime)'

I follow these steps: rails testApp --edge cd testApp rails g scaffold test hello:string rake db:migrate rake

I suposo this is a bug
