Help with Sofware Error? (Can't use an undefined value as an ARRAY reference at /usr/local/validator/httpd/cgi-bin/check line 571)

I'm seeing the following error message today and am unsure how to decipher it:

   "Software error:
   Can't use an undefined value as an ARRAY reference at /usr/local/validator/httpd/cgi-bin/check line 571.
   For help, please send mail to the webmaster ([no address given]), giving this error message and the time
   and date of the error. "

My question is:  
Is this an issue with the page I am trying to validate, or with the W3 validator?

(The page I am checking is not available with an address - if you need to see the code please let me know and I will forward to you.)
