Hi,

> - see any page except the login/signup page fail
> - downgrade to 1.8.6.114-2

I got the following error:

------------------------------------------------------------------------------
Ruby 1.8.7 has String#chars.
It returns an Enumerator object
but Rails 2.0.2 expects an ActiveSupport::Multibyte::Chars object.
You can avoid this conflict by putting
the following code in config/initializers/ directory.
------------------------------------------------------------------------------
unless '1.9'.respond_to?(:force_encoding)
String.class_eval do
begin
remove_method :chars
rescue NameError
# OK
end
end
end
------------------------------------------------------------------------------
Note: activesupport/lib/active_support/core_ext/string/unicode.rb
of Rails 2.1.0 removes "chars" method from String class of Ruby 1.8.7.
