Rails - Jan 2006 - app no longer runs - MissingSourceFile for any controller

Hello all.  I somehow managed to break my rails app running under Apache 2 
with fcgi.  With any action I try, it throws an exception saying it
can''t
find the source file.  For instance, requesting an action in my 
welcome_controller results in:
MissingSourceFile in <controller not set>#<action not set>
No such file to load -- app/controllers/welcome_controller.rb

The log doesn''t show anything, except the exception backtrace (below).
But, the application works fine using webrick.  Further, I''ve tried
running my
old todo app  (from the tutorial) with the same apache server, and it works 
fine.

What could be causing this problem?  Is there anything obvious I may have 
missed?  Thanks in advance.

Luca

ps:  in case it helps, here is the full backtrace of the exception

This error occured while loading the following files:
   app/controllers/welcome_controller.rb
Request
Parameters: None
Show session dump
Response
Headers: {"cookie"=>[],
"Cache-Control"=>"no-cache"}

Please use the Rails Engines plugin found here:

   http://opensvn.csie.org/rails_engines/engines/tags/rel_1.0.1

I appear to have broken stuff in the latest release. D''oh.
