This is a bug in FB 1.5.3 (haven't tried with FB 1.5.4 and FB 2.0.x),
which is fixed in FB 2.1 Alpha.

It has to do with granting field based update operations to users and
not removing the according record in the RDB$USER_PRIVILEGES table when
dropping the field. So there is a record in this system table for a
field which doesn't exist anymore.

Execute the proper REVOKE statement before creating a backup.

HTH.
