Another solution is also to overload the algebra_generators function for
group algebras.
Oops, I investigated this too quickly. The culprit is actually
Groups.ParentMethods.group_generators which returns self.gens() directly,
instead of making the result first into a family.

Thanks!

Hmm. Which patches did you have applied when you tried? Which version of
Sage?

Thanks!
