This is caused by Qt itself. Qt closes paths automatically if a path crosses itself. Thats why DRT results will never match the results of other ports. We already have bug reports about the different results, the Qt guys told me, that they won't change this behavior. So I think we can close this bug, or if this test is broken, upload a new baseline for Qt.
