Again, the given behavior is not a bug. It is similar to Mathematica returning x^(n+1)/(n+1) for the indefinite integral of x^n, or simplifying x/x to 1. You missed the part in the manual where it says that Integrate tries to find results that are correct for *almost all* (emphasis added) values of parameters. Bhuvanesh, Wolfram Research
