Signing eMails doesn't work anymore

[Richard Ulrich]

Hi, 

this is my first post to this list.

I have a crypto stick from www.privacyfoundation.de, and when I first
set it up, signing emails worked flawlessly.
But then I wanted to also be able to use my crypto-stick for ssh
authentication.
As adding the authentication sub key turned out to be difficult, I
generated an entirely new private key with encryption-, signature- and
authentication subkeys generated before putting them onto the crypto
stick.
SSH authentication works nicely now, but with the new key, signing
emails always fails. Ecryption and decryption still works. I'm using
evolution, but I also tried with thunderbird. The errormessage I get is
the same I get when trying to sign something with gpg directly. Could it
be that gpg is confused which key to use?



#gpg --sign setup_my_system.sh
gpg: sending command `SCD PKSIGN' to agent failed: ec=6.18
