I think that you are talking about different issue.  It's not a
problem of GnuPG (but problem of gnome-keyring), from the viewpoint of
mine.  In Debian, the bug reports in question are:

    SSH service: https://bugs.debian.org/623539
    gpg-agent: https://bugs.debian.org/760102

Per user basis, you can stop gnome-keyring for SSH service:

Or see the last message in 623539.

I do disable SSH service and gpg-agent emulation by gnome-keyring
system wide, because there are no reason to enable these (for me).
See:

I don't know if GnuPG 2.1 will be backported to Jessie or not.  Even
if it will be backported, you need to disable gnome-keyring services
of SSH and gpg-agent emulation (or expect gnome-keyring backport).

While 760102 was closed, I'm not sure about the current status for the
newer version of gnome-keyring interference for SSH service.


Well, I escaped from GNOME3.  However, newer xfce4-session has this
issue:

    https://bugs.debian.org/791378

I did:

  $ xfconf-query -c xfce4-session -p /startup/ssh-agent/enabled -n -t
bool -s false
  $ xfconf-query -c xfce4-session -p /startup/gpg-agent/enabled -n -t
bool -s false

to stop starting gpg-agent and ssh-agent by xfce4-session.
