Invalid - 'Stack level too deep' from calculations.rb:276 in beta3 on ruby 1.9.1

Hello, I am fairly new to the rails world and this is my first ticket.

As you may see in my full trace I am using ruby 1.9.1 and rails 3.0.0.beta3 and I am on a Mac OSX 10.5.8 (Leopard).

I started by just creating a new rails app with and then scaffoldings a new model and running 'rake db:migrate'. That is all, nothing else.

I am getting a 'stack level too deep' error and while running a full trace I was abel to find that the following was being looped over.

activesupport-3.0.0.beta3/lib/active_support/core_ext/time/calculations.rb:276:in compare_with_coercion'

I was able to find a quick work around here
#3808 Error creating Rails 3.0.pre Application

from bigtoe416 by running

bundle exec bash

and then I was able to migrate my database fine, however I think this is more or a band-aid to the actual problem.

Attached it my full trace without the looping
