new gnome-keyring interfering with ssh-agent

[Adam Funk]

I prefer to use ssh-add from the command line to manage keys.  The
recent distribution upgrade to 14.10 on one machine & yesterday's
upgrade to gnome-keyring:amd64 3.10.1-1ubuntu4.1 on another (still
running 14.04) have screwed something up so gnome-keyring-daemon is
preventing ssh-agent from running & is popping up the GUI for key
passphrases when I use the ssh client (& things running over it).

How can I disable this & get the old behaviour back?

Thanks,
Adam
