GnuPG 2.0.19 + Cryptostick - decryption fails with 4096 bit key

Hello,

I have recently generated subkeys to use with a GPF Cryptostick. I
decided to make full use of the ability to use 4096 bit keys with
recent versions of GnuPG ( > 2.0.18 I think). Everything is working
except when trying to decrypt a file or message encrypted to my
encryption subkey.

On this topic, I have found the following thread on the GPF forums,
which lead me back to this list.

https://www.privacyfoundation.de/forum/viewtopic.php?f=13&t=1145


The error output is the same as in the above thread, with no more
detail than:

gpg: public key decryption failed: General error
gpg: decryption failed: No secret key


Somehow, gpg2 is not able to read the key from the card. Is this a
known bug? I have not found anyone else documenting this.


Thanks,
Mat
