Changes (by kcrisman):

  * upstream:  Not yet reported upstream; Will do shortly. => Fixed
               upstream, in a later stable release.


Comment:

 This is fixed in the newest Maxima (5.24.0):

 Old:
 {{{

 (%i1) f:(x^2)*%e^x / (1+%e^x)^2;
                                      2   x
                                     x  %e
 (%o1)                             ----------
                                      x     2
                                   (%e  + 1)
 (%i2) integrate(f,x,minf,inf);
 (%o2)                                  0
 }}}
 New:
 {{{

 (%i6) integrate(f,x,minf,inf);
                                         2
                                      %pi
 (%o6)                                ----
                                       3
 (%i7)
 }}}
