Hi,

thanks very much for your help, it works now.

You were right, my PIN had a length of 5 and was still set to factory default.
After changing it all problems are gone.

Maybe the error message should be improved a bit to tell the user what is 
really wrong. I don't remember completely but I don't think gnupg showed an 
error when setting the short PIN.
