I'm using gnome-keyring with gpg and whenever I need to sign something, the keyring-daemon takes over and does it for me.

However, if I do: export GNUPGHOME=/path/to/keyring

from a bash-script and use gpg in that script, they keyring-daemon doesnt take over.

Why is this? How can I change this, so that the keyring is used for other $GNUPGHOMEs as well...?

If I do run seahorse, I can see that the password for the keys that exists in /path/to/keyring is there..
