gpg: key generation failed: Card error

Hi,

I cannot create keys on my shiny new v2 smartcard. Personalizing the
card works just fine, as does changing PINs.

But when I want to generate new keys I always get this error message
(after gpg asked about how long the key shall be valid):

gpg: key generation failed: Card error
Key generation failed: Card error

That's on a stock Slackware 13 system, gpg (GnuPG) 2.0.12, libgcrypt
1.4.4 with OMNIKEY CardMan 4040 v1.1.0gm5.

Any hints?

Okay, after much cursing omnikey I finally was successful in creating
keys on the smartcard using the SCR3310 smartcard reader. Someone
suggested updating to current gpg2 (2.0.13), that was the key to it
all.

Strangely the crappy omnicard reader has no problems at all reading
keys stored on the card. Still, I cannot recommend omnikey at all.

One question popped up in my mind on several occasions: V2 smartcards
supposedly cannot be bricked. So, how is the reset done exactly?
