Rails - Sep 2006 - render file in helper causes WSOD

If I use render :file=>... in a helper function, Rails dies with a 
white-screen-of-death (with nothing about it in development.log), but it 
works in a controller function, and other render functions (like render 
:text) work in the helper function.

# in helper - results in WSOD
module PagesHelper
  def body_render(page)
    case page.type.name
      when ''Markaby Template''
        render :file=>page.file, :layout=>false # WSOD
      when ''RedCloth Template''
        RedCloth.new(page.body).to_html # works, btw
      when ''Text''
        render :text=>''foo'' # works
    end
  end
end

# in controller - works
  def show
    @page = Page.find(params[:id])

    render :file=>@page.file
  end

# view
  body_render(@page.body)

Wrapping the render :file in begin/rescue/end also doesn''t trap
whatever
error is occurring.

Any ideas how to get this to work?

Thanks,
Joe
