I very much doubt it's a compatibility issue. PGP 8 imports the key from
the file and shows both userids on the key as Revoked. Neither userid has
a self-signature. Updating the key with the keyserver version adds
signatures and the missing self-sigs.

It would appear that the file version has been stripped and the validating
self-signatures also were deleted either in error or on purpose.
