Rails - Dec 2005 - observe_form without an update parameter

I''m using observe_form in a place that does not require any response 
from the server. So I do not use an update paramater. But without it 
webbrick hangs for a couple seconds and returns a status 500. On 
occasion, there will even be an exception in webbrick''s output if I 
change the form then quickly click a link before the couple second hang 
is done. If a add an update, it goes fast and returns status 200.

It seems it shouldn''t be necesary to have an update and an empty div
for
a action that always calls render :nothing => true

Is this a bug or am I missing something?

Thanks.
