[Rails] 404 and NameError

[jaikoo]

Hi guys,
I was wondering if anyone knew a fix for this problem I have. I've 
ported one of the apps I work with to Rails 0.10.0 to use Routes.
Everything works great, except for 404 pages.
The thing is that if I give a non existent path, I get the correct 404 
error page back. However if I request a non existent file such as 
test.php (in fact anything non existent that isn't a path really), I get 
a rails application error message on the screen and also a NameError in 
the logs. I've tried catching NameError for non local IP's, but this 
doesn't seem to get caught for some reason.

NameError (wrong constant name test.phpController):
