Rails - Feb 2005 - possible bug in options_for_select in actionview''s form_options_helper.rb

In form_options_helper.rb, the options_for_select function, line 56:

             is_selected = ( (selected.respond_to?(:include?) ? 
selected.include?(element.last) : element.las\
t == selected) )

This does the wrong thing when I pass in a list of [string, string] 
options and a string selected value.  What happens is that it does 
substring matches instead of whole string matches because String 
objects do respond to include?

More specifically, if I pass a list like this:

["than", "than"],
["bethany", "bethany"]

Both items are marked selected in the list since "bethany" includes 
"than".

I''m not sure what the right thing for options_for_select to do is here.
  It seems like it should test more explicitly for a collection instead 
of just the include? message.
