The problem is still there. Note that I've tried after upgrading then
rebooting the machine to make sure that nothing from old software was
running (in particular, I've noticed that otherwise, gpg-agent is
still running after I log out of all my X / SSH / screen sessions).

Basically:

1. Upgrade and reboot the machine A.

2. Log in with X.

3. Type "gpg -d file.gpg" and cancel at the pinentry-gnome3 prompt.

4. On some other machine, ssh to machine A.

5. In this ssh session, type "gpg -d file.gpg".

Result: A pinentry window is opened on the X display of machine A
and this gpg "freezes".

I confirm that the workaround (unset DBUS_SESSION_BUS_ADDRESS and
kill gpg-agent) still works.
