fastcgi_split_path_info capture group bug?

[uid_b]

I'm running nginx v0.8.54 (latest stable), and I'm having issues with
fastcgi_split_path_info passing the query parameters into PATH_INFO

e.g., http://example.com/index.php/foo/bar/?id=1 breaks is passed to
fcgi as
[code]
SCRIPT_FILENAME = /var/www/index.php          (good)
PATH_INFO       = /foo/bar/?id=1              (bad)
[/code]

I've defined the split in my config as:
[code]
  fastcgi_split_path_info ^(.+\.php)(.*)\??$;

  fastcgi_param SCRIPT_FILENAME   $document_root$fastcgi_script_name;
  fastcgi_param PATH_INFO         $fastcgi_path_info;
[/code]

The second capture group should only grab "/foo/bar/", am I doing
something obviously wrong here?
