Problem "Kobil Kaan Advanced" keypad [gnupg 2.0.18]

[Johannes Baiter]

Okay, I managed to resolve that problem by specifying the
`pinpad-program` option in gpg-agent.conf. I can enter the PIN now and
it is recognized ("Good PIN"-beep and the pin retry counter is not
decremented afterwards). However, the file is not decrypted and
scdaemon throws this (debug log):

Google-Fu did not yield anything for that specifiy error code :-/
