New description:
I test
{{{
sage: var ('n,k')
sage: sum (binomial(n,k)*k^2, k, 0, n) # is right
sage: sum (binomial(n,k)*k^2, k, 1, n) # is right n(n+1)2^(n-2)

This works correctly on Maxima 5.26 - we need to upgrade! The new spkg is
at
http://perso.telecom-paristech.fr/~flori/sage/maxima-5.26.0.p0.spkg
Install the spkg and apply:
