Bug#760102: gnome-keyring: Breaks gpg-agent with no UI to disable

[Mark Brown]

Package: gnome-keyring
Version: 3.12.2-1
Severity: important

Since a recent upgrade (sorry, not 100% clear when this happened but I
do update fairly frequently) gnome-keyring has started providing a GnuPG
agent.  This is breaking my usage of my system as gnome-keyring does not
appear to support GnuPG smartcards as gpg-agent does and my day to day
work is heavily dependent on being able to use one.  For example signing
e-mail causes this:

| gpg: WARNING: The GNOME keyring manager hijacked the GnuPG agent.
| gpg: WARNING: GnuPG will not work properly - please configure that tool to not interfere with the GnuPG system!
| gpg: selecting openpgp failed: Unsupported certificate
| gpg: signing failed: Unsupported certificate
| gpg: signing failed: Unsupported certificate

which is a serious issue; I also use my smartcard as a SSH key and this
usage is also broken.  There used to be a UI to edit the startup
applications but this seems to have been removed.
