rails 3 & nested layouts

Has anyone seen a solution for nested layouts that works with Rails 3? I’ve tried several previously documented patterns, including http://guides.rubyonrails.org/layouts_and_rendering.html#using-nested-layouts but keep getting no block given

thanks

Same problem. I tried this example from Rails Guide (it's been copied to Rails 3 version on http://guides.rails.info/) on a blank project both with ruby 1.9.1 and 1.8.7. Always the LocalJumpError - no block given. Actually I'm surprised I can't find any published workaround. That's not some subtle obscure little bug. Nobody's using nested layouts? I posted this question on stackoverflow. Still no suggestions.
