[regression][jaunty] gpg --recv-keys fails with "keyserver timed out" error

Binary package hint: gnupg

After Jaunty update anytime i want to request a key i get this error (IT):

gpg: richiesta della chiave xxxXXXxxx dal server xxxXXXxxxXX
gpg: keyserver timed out
gpg: ricezione dal keyserver fallita: errore del keyserver [download from keyserver failed: keyserver error, nda]

I tried many servers:
- wwwkeys.eu.pgp.net
- keyring.debian.org
- keyserver.pgp.com
- pgpkeys.mit.edu

Answer is always the same
