Same result from Maxima 5.27:
(%i1) display2d: false;
(%o1) false
(%i2) f: x/(%e^x - 1);
(%o2) x/(%e^x-1)
(%i3) integrate(f, x, 0, inf);
(%o3) 'limit(li[2](%e^x)+x*log(1-%e^x)-x^2/2,x,inf,minus)-%pi^2/6
more tests:
sage: giac('integrate(x / (exp(x) - 1), x, 0, inf)')
pi^2/6
sage: integrate(x / (exp(x) - 1), x, 0, oo, algorithm='sympy')
integrate(x/(e^x - 1), x, 0, +Infinity)
i think this is another reason to make more user friendly the functionality that is offered through giac; stay tuned at the giac interface wiki.

We expect,
but get,
The above might not be incorrect, but it is not very useful either.
