gpg: key E22EAB4D: secret key without public key - skipped

[Andreas Siegert]

Hi,

I see the following message ever since I imported some old RSA keys of mine
from pgp 2.x:

gpg: key E22EAB4D: secret key without public key - skipped

every time I encryt something.

When I do a gpg --list-secret-keys I see the old key.
When I use  gpg --delete-secret-key E22EAB4D then I get the message 
gpg: key E22EAB4D: secret key without public key - skipped
gpg: E22EAB4D: user not found
gpg: E22EAB4D: delete key failed: secret key not available

Is there a flag to fix this?
gpg --version
gpg (GnuPG) 1.0.6
...
Cipher: IDEA, 3DES, CAST5, BLOWFISH, RIJNDAEL, RIJNDAEL192, RIJNDAEL256,
TWOFISH
Pubkey: RSA, RSA-E, RSA-S, ELG-E, DSA, ELG
Hash: MD5, SHA1, RIPEMD160

thx
afx
