Thank you for your bug report and your opinion.  The cause is GNOME
keyring, but, I agree that it's a kind of bug of GnuPG and friends
from users' point of view.

For years, I have been struggling to disable this "feature" of GNOME
Keyring.

Last month, I wrote to its maintainer (when asked):

    http://lists.gnupg.org/pipermail/gnupg-devel/2014-August/028691.html

In the message, I only addressed about smartcard/token and SSH.

Your bug report is another important case.
