[pkg-gnupg-maint] Bug#919856: Bug#919856: gpg-agent: agent refuses operation again

[NIIBE Yutaka]

Hello,

It looks like similar to the bug 835394.

Manual workaround to set environment variables is:

	$ gpg-connect-agent updatestartuptty /bye

As explained in:

It may happen when gpg-agent doesn't know DBUS_SESSION_BUSS_ADDRESS.

It may happen when gpg-agent doesn't know DISPLAY or XAUTHORITY.
