Subject: Plugin if statement not working :(

I'm having a bit of trouble with a Mephisto plugin that doesn't seem to
want to work right.  The articles_by_month_and_year won't detect an
empty return at all.  For example if they go to /archives/2007/08 and
there are no articles it doesn't return a 404 and if they go to
/archives/200(6|8|9) it doesn't return a 404 either.  Can somebody help
me figure out what I'm doing wrong?

module MephistoFullArchives
  module MephistoController

    def self.included(base)
      base.send :alias_method_chain, :dispatch_archives, :full_archives
    end

    def dispatch_archives_with_full_archives
      if params['path'].length < 4
        # 3 or Less
        # Year and Month + Archives
        render_liquid_template_for(:archive, 'section' => @section,
'articles' => articles_by_month_and_year);
      else
        # Return 404 on Day
        # Do people actually want archive links for days?
        if params['path'].length == 4
          show_404 and return
        else
          # Anything else might be an archive
          # Let Mephisto deal with it.
          # On a general basis Mephisto does alright with it.
          dispatch_archives_without_full_archives
        end
      end
    end

    def articles_by_month_and_year
      archives = []
      archives = @section.articles.find(:all, :include => :user,
:conditions => ['contents.published_at IS NOT NULL'], :order =>
'contents.published_at DESC')
      if @archives.nil? or @archives.empty?
        show_404 and return
      else
        @articles = archives
      end
    end

  end
end
