Upgrading to libgcrypt11 1.4.0 generates a different error. However
I think this one is really a gnupg2 error, not a gcrypt one.

Please select what kind of key you want:
   (1) DSA and Elgamal (default)
   (2) DSA (sign only)
   (5) RSA (sign only)
Your selection? 1
DSA keys may be between 1024 and 3072 bits long.
What keysize do you want? (1024) 2048
Requested keysize is 2048 bits
ELG keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048)
Requested keysize is 2048 bits
Please specify how long the key should be valid.
         0 = key does not expire
      <n>  = key expires in n days
      <n>w = key expires in n weeks
      <n>m = key expires in n months
      <n>y = key expires in n years
Key is valid for? (0)
Key does not expire at all
Is this correct? (y/N) y

You need a user ID to identify your key; the software constructs the user ID
from the Real Name, Comment and Email Address in this form:
    "Heinrich Heine (Der Dichter) <heinrichh at duesseldorf.de>"

Real name: hjjh
Name must be at least 5 characters long
Real name: gghghgjgj
Email address: fgfgfh at gjhgkhkh
Comment:
You selected this USER-ID:
    "gghghgjgj <fgfgfh at gjhgkhkh>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? o
You need a Passphrase to protect your secret key.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
gpg: WARNING: some OpenPGP programs can't handle a DSA key with this digest size
gpg: DSA key BEB7B76F requires a 224 bit or larger hash
gpg: make_keysig_packet failed: General error
Key generation failed: General error
----------------------

I will re-assign to gnupg2 once libgcrypt11 1.4.0
is in unstable.
