Good job tracking this down; this is pretty tricky :-) In principle,
that was fixed two weeks ago:
changeset 1699:9d173b1a529d: Fixed guard on #6597 which caused it not to apply
on 4.1.1 and broke algebras
When did you last install/update?

Thanks for pointing this out. There indeed are a couple of them
left. Could you please fix them? We currently don't have a specific
policy for who does this: whoever needs (to fix) such a guard just
does it.
