[Pkg-gnupg-maint] Bug#642512: gnupg --recv-keys says "key xxx not found on keyserver" when a proxy refused connexion with 503

[Yann Dirson]

Package: gnupg
Version: 1.4.11-3

This happens when the HKP port is filtered by a HTTP proxy.
A message like "Proxy could not contact the server" would be much more accurate...

Here is what the user gets:

$ gpg --recv-keys 03A3F7F5
gpg: requesting key 03A3F7F5 from hkp server keys.gnupg.net
gpgkeys: key 03A3F7F5 not found on keyserver
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

While strace reveals:

3599  recv(5, "HTTP/1.0 503 Service Unavailable"..., 16384, 0) = 1566
