The 01000000000000000000000000000001 serial number is just a "placeholder" 
non-existent serial number we put in our CRL files if there are no revoked 
certificates under the CA certificate.  We added it around 2007 or 2008 to work 
around a problem that existed in a Novell server software (now I can't remember 
the name of it) which would throw an exception and fail to assign a certificate 
if the CRL had zero revoked entries.  

Thanks for reviewing Erwann!
