What about

elt = dict({ x for x in dict(HLP(m(la))).iteritems() if x[0] in self._kbounded_partitions })

in src/sage/combinat/sf/k_dual.py?

I can review this one.

Seems to be OK and tests passed. Feel free to mark as positive_review now, of check src/sage/combinat/sf/k_dual.py, whichever you want.

Thank you, Jori.

I have found another missing case, and treated it too.
