gpg smartcard troubles

[Albert Dengg]

hi

currently i had to switch from my notebook to my workstation and i now
have a problem:
while my openpgp smartcard works with gpg-agent (ssh auth works), i'm
unable to decrypt files encrypted for the encryption subkey or signing
with the sign subkey, though they are listed when i do a "gpg
--edit-key" as beeing subkeys...

any ideas what's going wrong or how i can tell gpg where to find the
secret subkeys?

tia

yours
albert
