[pkg-gnupg-maint] Bug#801247: pinentry-gnome3: No PIN dialog

[Tim Small]

Package: pinentry-gnome3
Followup-For: Bug #801247

In my case, it looks like:

gpg-agent is started, and inherits the DBUS_SESSION_BUS_ADDRESS env
varible.  The gpg-agent persists across login sessions, so that when it
starts the gnome3 pinentry the dbus session doesn't correspond with the
current desktop session.

The practical result of this is that when I log to X first, it works,
but if I subsequently logout of my X session and then login again, I see
this bug.

People who start gpg-agent (or their X server) in different ways are
likely to see this problem without session restarts I suppose.

To confirm, I get different results from:

grep -z -i dbus  < /proc/`pidof gpg-agent`/environ

vs. 

grep -z -i dbus  < /proc/$$/environ

The gpg-agent manual page documents the use of:

gpg-connect-agent updatestartuptty /bye

to change the TTY and/or X display used for pin entry prompts.

I suppose the fix would involve either pinentry-gnome3 getting the
dbus session from the X session in some way (if that's possible),
or extending the functionality of "updatestartuptty" to also update dbus
session used by gpg-agent when starting the pinentry command.

Cheers,

Tim.
