This is probably caused by a database error at the certificate issuer's end
(Thawte). The error is currently considered fatal, and you would see the same
result if you activate OCSP in Firefox (and probably IE. I am not sure what
would happen in Vista, but Microsoft has stated that they are going to active
OCSP by default there).
We've seen a number of these recently, and I've just informed my contact at
Verisign (which owns Thawte) about the problem.
