I'll just confirm the above and add that even executing

    gpg-connect-agent updatestartuptty /bye

on the remote ssh session shell (Bash) doesn't help. I tried
gpg+pinentry with this command on the remote ssh session:

    gpg -ac <<< message

and pinentry-gnome3 opens its password prompt window in the running
desktop session (XFCE4 in my case).

My test environment is the current Debian testing in virtual machine
(Qemu) and ssh connection was made from the host machine.
