[Rails] Intermittent problem with link_to_remote()

Hi folks,

My page displays links for ''categories'' using the
link_to_remote()
function.   Clicking on one of these links goes to the controller and
returns any child categories.    I''m finding that the page works ok but
after a number of clicks (average 5 or so), it crashes with an error:

127.0.0.1 at 2006-01-04 15:26:28) [POST]

If you are storing Listing objects in your session, rather than just their
