rails bug: incorrect sql generated or no error checking performed

I wrote the following rails code in one of my models:

     su = self.find(:first,
            ["scrape_type = ? and finished = 0", scrapetype],
            :order=>"updated_at");

According to development.log, this generated the following SQL:

    SELECT * FROM scrape_urls ORDER BY updated_at LIMIT 1

Note that the man page
http://rubyonrails.org/api/classes/ActiveRecord/Base.html contains an
example with the above format:

Company.find(:first, [
    "id = :id AND name = :name AND division = :division AND created_at

:accounting_date",

    { :id => 3, :name => "37signals", :division => "First",
:accounting_date => '2005-01-01' }
  ])

Bug #1: Since rails ignored the array that I supplied, Rails should
have generated an error.

Bug #2: The documentation is probably incorrect. I currently suspect
that the phrase ":condition=>" should appear before the open bracket.

Bug #3: It's too hard to figure out how to submit a bug report to
rails. Hope you guys find this and fix your code.

This is the case.

rails. Hope you guys find this and fix your code.
