Serious Bug in symbolic processor

I ran into what seems to be a very serious bug with the symbolic engine. A rather basic Integral is evaluated wrong. See the picture what it look like. The MC version is MC14-M030. The bug does not show up with version 11. From collabs I heard that the bug does not show up with Mathcad14-version 14.0.0.163 (is this M011??). This would be rather curious. Anyway - anybody figure out whats going on her or has a workaround? Feel a little bit concered not knowing what other results will be as wrong in oter calculations. W. Exinger 15.3.2010: According to PTC-Support the bug is known and already fixed in M040. He couldn't tell me when M040 is scheduled. Personally I thought the next release would be MC15 in June or July.

Forgot to add, make sure you have Mathcad 14.m20. You can get it from the link below.

Mathcad 15 is available now, and does this integral correctly.
