One flaw I see here is you are not in taint mode. I'm not completely clear why you think that way is any better or safer (on its own) than using Location (or CGI.pm's redirect() method). In any case, without taint checking in your example, you are left open to ../../../../../etc/passwd being passed as the filename.

You mentioned that you attempt to do this when _you_ parse QUERY_STRING, but I wonder why you are doing this instead of using CGI.pm or CGI_Lite.
