I did not phrase it properly, leading to a misunderstanding.
We are talking about using a smartcard on a compromised computer. I
reasoned from the OpenPGP Card specification. You can simply ask the
smartcard for the public key; the actual cryptographic public key.
So as an attacker with control over the computer, you see that someone
succesfully decrypts a document using his OpenPGP card. You ask the
smartcard for the public key that was used to encrypt the document, and
you have a fully unique identifier for the key that was used.
 It isn't clear to me whether this project is actually adhering to
the OpenPGP card specification, though, I didn't check. I realised this
I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
