Routes Problem

Hi Everyone -

I think I may have found a problem with the Routes in Rails 0.10. I  
have a controller called "survey" with a "list" action that
does
pagination of a list of surveys filled out by users. So to view page 2  
of the listing, the URL is something like

	http://foo/survey/list?page=2

I upgraded the app to Rails 0.10 and everything was working great until  
I added a custom Route. Here''s the whole routes.rb:

ActionController::Routing::Routes.draw do |map|
   map.connect '''', :controller =>
''survey'', :action => ''list''
   map.connect '':controller/:action/:id''
end

So now the URL http://foo/ correctly shows the output of my survey  
controller''s list action. Great.

However, the URL that the pagination helper generates for page 2 of the  
listing is now

	http://foo/?page=2

When I follow this link, I get a 500 response from Apache and the  
following in apache.log:

I tried delving into the Rails internals identified in the stack trace,  
and quickly got way over my head :-).

Help!
