in_place_editor isn't working?

I installed the in_place_editor plugin from http://dev.rubyonrails.org/svn/rails/plugins/in_place_editing/

This is what I have:

<%= in_place_editor_field :frontpage, 'page_text', :in_place_editor_options => { :rows => '30', :cols => '20', :save_text => 'do this' } %>

This is what I get:

<span class="in_place_editor_field" id="frontpage_page_text_1_in_place_editor" in_place_editor_options="cols20save_textdo thisrows30">Placeholder text for the frontpage.</span><script type="text/javascript">

new Ajax.InPlaceEditor('frontpage_page_text_1_in_place_editor', '/ frontpage/set_frontpage_page_text/1')

It seems like in_place_editor_options is being co-opted as tag_options. Am I a moron, or is something going wrong?
