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)
sage: sum (binomial(n,k)*k^2, k, 2, n) # is false : I get 0

This works correctly on Maxima 5.26 - we need to upgrade!
The new spkg is

Comment:
Several doctests need to be patched due to changes in output format/term
order. See
