Package: maxima
Version: 5.10.0-6
Severity: normal

integrate((1+x1+x1*x2)^(-3)*(1+x2+x1*x2)^(-3), x1, 0, 1);

maxima asks a couple of questions and loops forever.

A possible work around is

map(lambda([u], integrate(u, x1, 0, 1)),
    map(factor, partfrac((1+x1+x1*x2)^(-3)*(1+x2+x1*x2)^(-3), x1)));

It would be nice if maxima could compute simple integrals like this without
any non-trivial effort from the user side.
