I did a quick check and I can't find a difference in the code. Do
youuse the same config file? Note that gpg tries to read a gpg.conf-2
file first. If David has no other idea, I'd ask you to send me that

I am not sure whether this works. We probably never tested the case
to rectify an invalid cross-signature:
(en)If you have been pointed to this page by someone who received
a warning when verifying one of your signatures, your key does
not contain a subkey cross-certification. You can easily add
this cross-certification using GnuPG 1.4.3 or later. To do
this, simply run "gpg --edit-key (yourkey)" and then enter
"cross-certify". You'll need to type your passphrase, and
GnuPG will add the necessary cross-certification. Once this
is done, you should distribute your key however you like (send
it to a keyserver, post on a web page, etc). If you have
already done this and people are still receiving the warning,
make sure they have updated their copy of your key from the
keyserver or web page.
Die Gedanken sind frei. Auschnahme regelt ein Bundeschgesetz.
