Using a component with Component {} as the root element as another file Component again crashes in QDeclarartiveComponent

Using a component with Component {} as the root element as another file Component again crashes in QDeclarartiveComponent.

If you have for example a component like flickr/mobile/ListDelegate.qml

Component {
    Item {
        id: wrapper; width: wrapper.ListView.view.width; height: 86
        Item {
          [...]
        }
    }
}

Then using this component as a root component like this:

test.qml:

import QtQuick 1.0
import "mobile" as Mobile
Mobile.ListDelegate { }

will crash.

Since we sometimes turn elements into components in the tooling this leads to problems.
