If you do string.last or string.first it fails in access.rb line 43 I  
found the answer on another mailing list.

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.
