Sorry I wasn't clear -- my intention was to report the bug. I can
integrate 1/x, thank you :-)

The example I posted is symptomatic of a problem with Integrate that I
stumbled upon while solving a more complicated problem. I
intentionally kept it trivial to make it obvious. This said, I don't
quite understand your argument that it's somehow okay for Mathematica
to give the wrong answer on a trivial problem because no sensible
person should use it to solve such a problem...
