openpgp card woes: 'secret key not available'

[Wouter van Heyst]

Hi all,

in my ongoing quest to make use of my OpenPGP card I've finally managed
to add several card subkeys to my key following
http://www.fsfe.org/en/card/howto/subkey_howto

However, I seem to have done something wrong (again):

 > gpg -ev msg
 gpg: using subkey B0DACEAB instead of primary key 0DC0B7D6
 gpg: reading from `msg'
 File `msg.gpg' exists. Overwrite? (y/N) y
 gpg: writing to `msg.gpg'
 gpg: RSA/AES encrypted for: "B0DACEAB Wouter van Heyst <larstiq at larstiq.dyndns.org>"

So far, so good.

 > gpg -vd msg.gpg
 gpg: public key is B0DACEAB
 gpg: using subkey B0DACEAB instead of primary key 0DC0B7D6
 gpg: detected reader `SCM SCR 335 (21120617208489) 00 00'
 gpg: reader slot 0: active protocol: T1
 gpg: slot 0: ATR=3B FA 13 00 FF 81 31 80 45 00 31 C1 73 C0 01 00 00 90
 00 B1
 gpg: AID: D2 76 00 01 24 01 01 01 00 01 00 00 03 54 00 00
 
 PIN
 gpg: verify CHV1 failed: invalid passphrase
 gpg: using subkey B0DACEAB instead of primary key 0DC0B7D6
 gpg: encrypted with 1024-bit RSA key, ID B0DACEAB, created 2006-08-15
       "Wouter van Heyst <larstiq at larstiq.dyndns.org>"
 gpg: public key decryption failed: invalid passphrase
 gpg: decryption failed: secret key not available


gpg complains about an invalid passphrase, but it didn't even prompt for
one. I'm also not sure what the 'secret key not available' is about,
according to `gpg --card-status`:

 Encryption key....: 6D70 3242 0A9E A10F 2A57  9E88 D886 E99A B0DA CEAB
       created ....: 2006-08-15 13:37:02

I've ensured gpg-agent and/or scdaemon are not running, they have caused
weird problems in the past. Not sure what is wrong now.

mvgr,
