I reported the issue upstream and Werner Koch wrote:
--------------------
gpg1 does not known about keygrips. Instead of the keygrip, gpg1 uses the
fingerprint as cacheid for gpg-agent. The agent's command GET_PASSPHRAE, as
used by gpg1, uses a different cache mode from what gpg-preset-passphrases uses.
Thus even if you replace the keygrip with the fingerprint of the (sub)key, it
won't work.
I'll add
Note, that the tool @command{gpg-preset-passphrase}, which comes
with GnuPG-2, cannot be used to preset a passphrase for this
version of GnuPG.
to the gpg 1 man page.
--------------------
When this change makes it into the documentation, i'll close the debian bug.
