Bug#790049: SSH_AUTH_SOCK no longer set in environment

[Josh Triplett]

Package: gnome-keyring
Version: 3.16.0-2
Severity: normal
File: /usr/bin/gnome-keyring-daemon

Recently, I noticed that gnome-keyring's SSH agent no longer seems to
set SSH_AUTH_SOCK in the session environment.  I can see via ps that the
SSH component is running:

josh      2321  0.0  0.1 419788  8108 ?        SLl  08:48   0:00 /usr/bin/gnome-keyring-daemon --start --components=ssh

However, nothing sets SSH_AUTH_SOCK in the session environment anymore.
(I have no-use-ssh-agent in /etc/X11/Xsession.options temporarily, to
prevent ssh-agent from running, as I'd prefer to use the SSH agent in
gnome-keyring.)

I noticed this when automated invocations of SSH stopped working.  For
instance, I have mutt configured to use an SSH tunnel.  With
gnome-keyring's SSH agent configured, gnome-keyring prompts for the
passphrase when I run mutt.  With ssh-agent (without a manual ssh-add)
or no agent configured, mutt just says that the tunnel failed.  (One of
many reasons I prefer to use gnome-keyring: the automatic prompting and
adding.)

(As an aside, does gnome-keyring-daemon with --components contact a
running instance of itself and add that component, rather than running a
separate instance?  Because I only ever seem to have one
gnome-keyring-daemon running, and it seems non-deterministic whether
it's the one with --components=ssh or --components=gpg, yet all of the
sockets exist in /run/user/1000/keyring, and messages in the session log
seem to suggest that at least the SSH and GPG components are running.)
