It's late and maybe I'm wrong but there seems to be an infinite recursion error (Firebug says "too much recursion") when multiple dd tags are used inside a dt tag. Maybe the plugin was never meant to be used with this html structure.
Example: http://rmip.com/accordion/ Top example has the problem. Error occurs on clicking a heading. The bottom doesn't. jQuery version is 1.1.4. Erin
