No clue, but I suggest you to add some:

>  $stderr.puts "TEST X: #{cgi.params.inspect}"

...all over that dispatcher script to see where the problem starts (it will 
log to lighttpd's error log).

 I also had many problems with fcgi and lighttpd mainly because it was setting 
different environment variables than other webserver (webrick). To fix this I 
first modify the environment table before I continue and so far I have no 
problems:

... and in the dispatcher you do:

>  FCGI.each_cgi do |cgi|
>    CGI::fix_env(cgi.env_table)


Maybe that helps...
