On the one hand, it appears to be a bug.  On the other, I don't think
it's a bug in nginx.  The FastCGI is just receiving the variables over
the socket, including SCRIPT_FILENAME.  It would therefore be a bug in
the program receiving from the CGI side (I'm guessing PHP?).  By the
way, SCRIPT_FILENAME is not a standard CGI meta-variable.

http://tools.ietf.org/html/rfc3875#section-4.1

4.1.  Request Meta-Variables

   Meta-variables contain data about the request passed from the server
   to the script, and are accessed by the script in a system-defined
   manner.  Meta-variables are identified by case-insensitive names[.]
