Thanks. I consider this a bug though it might be
more precisely described as an unimplemented feature
(I'm guessing that there is no __mul__ method in the appropriate
class). Until it gets fixed, here is a workaround:
sage: f = maxima.function('x', 'sin(x)')
sage: g = f.integrate("x")
sage: h = maxima.function('x', "("+str(f)+")*("+str(g)+")")
sage: f; g; h
sin(x)
-cos(x)
(sin(x))*(-cos(x))
Could you please post this to the bug tracker?
