Did you look for "Explicitly Disabled DigiNotar..."?

Not really, since DigiNotar's CA is cross-signed by Entrust and it probably 
won't know that that signature has been revoked, since GnuTLS doesn't support 

That's the same sad story for everything else using GnuTLS and for many 
OpenSSL users. OpenSSL does support OCSP, but applications rarely use it.

From mozilla's bugzilla, these should also fail:

(disable online recovation check before testing, at least the last one)
