OpenPGP Card - general error unblocking PIN

[Tiago Faria]

Hi list,

I've been giving the OpenPGP card a try, and a ran into a problem when
changing/unblocking my PIN.

After a few Google searches I noticed other people also experienced this
problem, however, I couldn't find a solution.

GnuPG is version 1.4.9 and I'm using the second version of the card. 

I've included the debug information of the passwd > unblock PIN
command, even though the Change PIN doesn't work either:

------- Debug Log -------

Error unblocking the PIN: general error

1 - change PIN
2 - unblock PIN
3 - change Admin PIN
Q - quit

------- Debug Log -------

One thing I also noticed is that the PIN retry counter has the
following values: 3 0 3

According to the documentation, the first value and second should be in
sync.

Any tips would be appreciated. Thank you very much for any help.
