QML crashes when declaring a list with primitives

(tested with gitorious master)

The following qml snippet crashes:

import Qt 4.7

Rectangle {
id: root
width: 450; height: 450
color: "black"

children: [
//Rectangle

{id: childRec1; x: 50; y: 50; height: 50; width: 50; color: "red"}

,
//Rectangle

{id: childRec2; x: 150; y: 50; height: 50; width: 50; color: "yellow"}

1, 3
]

}

Of course, it's invalid, but it should generate an error message printed to the console, not a crash. If needed I could provide a patch (via gitorious merge request).
