That's not a bug.  That's inherent in the design of the keyservers.
If a program asks for "X" and two keys have key ID "X", then you get
them both.  Nothing can be done about that.  Of course, you won't have
any trust in the other key.

GnuPG will use the maximum key ID size it can.  If you are using
--refresh with a LDAP keyserver, it uses the 64-bit key ID which makes
this sort of thing much less likely.  Of course, there is only one
LDAP keyserver left for public use.
