You had a user with usesysid 128, whom you dropped, but he still had
privileges on some tables --- DROP USER is not good about detecting
dangling references.
I'd suggest recreating the user (CREATE USER foo WITH SYSID 128) and
then being careful to REVOKE all his privileges before you drop him
again. Or you can just manually edit the dump file to remove the
attempts to GRANT him privileges.
