Decryption troubles

Hello,

There are two encryption keys as far as I can see (more complete key in
attachment). Probably one of them was added but the secret key has been
lost (during migration? I don't know).

I've suggested checking which one works for them and revoking the other,
and then publishing the key to keyservers (that was some time ago,
that's how I've got this key with two E keys).

By the way of two encryption keys, I liked your idea:

"+  0x04 - This key may be used as an additional decryption subkey (ADSK)."

Kind regards,
Wiktor
