Rails - Jun 2010 - ActionController::RoutingError in Posts#index

Not sure what happened to my last post so I will try again, here goes...

I am getting the following error and not sure why?  I think its because
I am sending over an id when I shouldn''t be. I was logged into my app
when I created this code referenced below and all was fine.  I then
logged out and now I am getting this error everywhere and can''t even
get
into the log-in screen without commenting the code out.  Any
suggestions?

Showing app/views/pages/_stats.html.erb where line #4 raised:

subscribing_user_url failed to generate from {:controller=>"users",
:action=>"subscribing", :id=>false}, expected:
{:controller=>"users",
:action=>"subscribing"}, diff: {:id=>false}

Extracted source (around line #4):

1: <% @user ||= current_user  %>
2:   <div class="stats">
3:     <h1>
4:       <a href="<%= subscribing_user_path(@user) %>">
5:         <span id="subscribing" class="stat">
6:           <%= @user.subscribing.count %> subscribing
7:         </span>

Ok, think I figured it out.  @user and current_user are both nil and so 
thus the error.  So put in the following and seems to work.

<% @user ||= current_user  %>
<% if @user %>
.......
<% end %>
