OK, I (finally) was able to reproduce it consistently, but SSH was
actually not "necessary" to see it:
(no, I'm not doing anything "funny": I have a backup =P)

Nothing strange here... but actually the .gnupg directory is "green"
(EFS-encrypted).

Any idea?

Oh, I just noticed this also:

% rm /home/lapo/.gnupg/secring.gpg
% ll -a /home/lapo/.gnupg/secr*
ls: /home/lapo/.gnupg/secring.gpg: No such file or directory
- -rw-------  1 lapo Nessuno 7736 Mar 24 23:47 secring.gpg.tmp

...but with Windows Explorer, the file is still there.
