Rails 2 problem with compute_public_path

I'm trying to migrate to Rails 2, but keep getting these errors all
over the place:

ActionView::TemplateError: wrong number of arguments (2 for 3)
    On line #61 of users/new.rhtml

    58: <% if @captcha_error -%><div class="fieldWithErrors"><
% end -%>
    59: <table class="signup"><tr>
    60: <td class="signupdescription">Verification
code:<br /></td>
    61: <td><%= image_tag
@captcha_image.public_filename, :size=>@captcha_image.image_size %></

    62: </tr><tr>
    63: <td class="signupdescription"
rowspan="2">Enter code:</td>
    64: <td><%= text_field_tag :code %></td>

    vendor/rails/actionpack/lib/action_view/helpers/
asset_tag_helper.rb:390:in `image_tag'
    app/views/users/new.rhtml:61:in

    vendor/rails/actionpack/lib/action_view/helpers/form_helper.rb:
224:in `fields_for'
    vendor/rails/actionpack/lib/action_view/helpers/form_helper.rb:
184:in `form_for'
...

Basically, every function that calls `compute_public_path' gets this
error. In this case, it's 'image_tag'.
I'm looking at the source and don't see any problem.

      def image_path(source)
        compute_public_path(source, 'images')
      end

      def compute_public_path(source, dir, ext = nil, include_host =
true)

compute_public_path takes a minimus of one parameter, which is
supplied by image_path.

What am I doing wrong here?

You probably have a plugin, like asset_packager, overriding tag_options.

Or image_path..

Nice catch Jeremy,

I'll patch asset_packager for Rails 2.
