Of course it should not crash.
I get an ASSERT: "mo" in file qml\qqmlvme.cpp, line 849 (this is with current stable branch though).

I'm a bit curious to know why do you want to animate that property?
What do you want to achieve?

I thought something as simple as:

            Behavior on Layout.preferredWidth {
                NumberAnimation { duration: 1000 }

would do.. Apparently not since it crashes qmlscene..
Do i need to do it differently or did i just hit a bug?

Version details:
Qt 5.1.0 x64 (i know, 5.1.1 is out)
Mac Mountain Lion fully updated
