I'd like to help fix this but I don't know much about the Qt port.  I can tell you about the patch that introduced the test however.

r71314 was introduced to fix an issue in the way animated path transforms interact with container transforms.  The test (svg/animations/animate-path-nested-transforms.html) fails with the old behaviour, and (at least in webkit main) passes with the new behaviour.

The test looks at the starting and ending bounding box of an animated square, to make sure that the square moves overall horizontally more than vertically.

Looking at the output of the test for the Qt port, it seems that the animation proceeds correctly, but that the start and ending locations are slightly incorrect.  I am unable to run this test on a linux machine (at least not for another week) to confirm this, but it almost seems as if the bounding box is larger when the test is run using Qt.  If this is the case, then this specific test can be fixed by providing expected results for Qt that roughly match the output (e.g. (360, 270) and (700, 230)); however I'm also quite curious as to why the values are so different.
