If you're worried about this you should be able to find a smartcard
reader with PIN entry that GnuPG supports. That way you never enter your
PIN on the computer.

It doesn't prevent a trojan from signing something other than what you
intended (if it's your master key on card, even another key or a new
sub-key) but whether this is a problem depends on your threat model.
