lighttpd forum lighty > Fastcgi + Python - spawning not working

Hi all,
I am trying to get python + fastcgi work on Lighty 1.4.18. I'm following 
the instructions here - 
http://cleverdevil.org/computing/24/python-fastcgi-wsgi-and-lighttpd.

That mostly works, except for one case. I am unable to have Lighty spawn 
the test.fcgi script and have it work. I think the script is being 
spawned, however, the script does not seem to respond. I am clueless as 
to what could be the problem.

Note that everything works fine if I manually start the test.fcgi script 
(i.e.  I get back a 'Hello World!')

I am attaching the relevant code:

lighty.conf
-----------
fastcgi.debug = 1
fastcgi.server = ( ".fcgi" =>
    ( "localhost" =>
         (
#          "min-procs" => 1,
#          "max-procs" => 1,
          "socket"    => "/tmp/fcgi.sock",
          "bin-path"  => "/home/praveen/web/test.fcgi"
        )
    )
)

Any idea what I am doing wrong? Thanks in advance.
