Comment (by cnassau):
I actually don't care about {{{Permutations()}}} a lot - I just picked
those to come up with an easily reproducable problem. I should have given
this example:
{{{
sage: X=CombinatorialFreeModule(ZZ,ZZ)
sage: print X
Free module generated by Integer Ring over Integer Ring
sage: print X.basis().category()
Category of enumerated sets
sage: TX = tensor((X,))
sage: print TX.basis().category()
Category of finite enumerated sets
}}}
I believe I fixed this in #13979 for Sage 5.7.b4 (which was neither merged
nor even considered).
