Thank you for your quick reply, Stef.  Yes, Debian's packages' versions 
usually lag behind,  And yes,  I run all my applications fullscreen 
because I'm on a netbook with a small screen.  The application which 
runs GPG2 which calls Seahorse is GNU Emacs, running fullscreen.

After sending my request for support, I've tried to configure GPG2 
(version 2.0.17) to use an alternative to Seahorse and I have not been 
able to restore my previous configuration.  I've put together a a 
minimal testing procedure which I hope will work for those who still 
have GPG2 calling Seahorse.  Software used, besides that documented in 
my quoted mail:
- GPG2 2.0.17;
- GNU Emacs 23.1 or later.

Here we go:
- launch some applications - like Firefox, Thunderbird and Terminal - 
then press F11 to maximize them;
- create an ~/.emacs text file with this content:

(require 'epa-file)
(setq epa-file-cache-passphrase-for-symmetric-encryption t)
(setq epg-gpg-program "gpg2")
(epa-file-enable)
(run-with-idle-timer 1.0 nil (lambda ()
		  (set-frame-parameter nil 'fullscreen 'fullboth)))

- launch "emacs": GNU Emacs should start fullscreen;
- press Control-x and then Control-f: you should be prompted for a filename;
- enter a file name ending with ".gpg";
- type something into such file;
- press Control-x and then Control-s: this is to save your file;
- click on [OK] in the textual popup raised by Emacs;
- Seahorse should popup;
- press Alt-Tab or click on the Emacs window: Emacs should become the 
foreground window;
- now your desktop should be locked.

Cheers.
