A bug in his software (CryptoEx) would explain nearly everything
here.  Since CryptoEx naturally would be compatible with itself, it
would see the keyid as 3A546EC2.  It would fill in 3A546EC2 as the
issuer of signatures, and it would be able to verify its own
signatures so the key would be valid.

That theory doesn't explain why the keyservers indexed the key as
3A546EC2 though.  GnuPG, PGP 6 and 8, and my local copy of pksd all
agree the keyid is 7EDB7A47.
