QML Camera viewfinder broken when not using camerabin backend

When using the QML Camera element the viewfinder is not displayed although the camera turns on.
The demo camera application displays the symptoms as does the simple QML file

import Qt 4.7
import Qt.multimedia 1.1

Rectangle {
width: 640
height: 480

Camera

{ anchors.fill: parent }

}

displaying the errors:
> qmlviewer Camera.qml

(<unknown>:20304): GStreamer-CRITICAL **: gst_bin_add: assertion `GST_IS_ELEMENT (element)' failed

(<unknown>:20304): GStreamer-CRITICAL **: gst_element_link_pads_full: assertion `GST_IS_ELEMENT (dest)' failed

This has been fixed on QT-mobility git master as commit http://qt.gitorious.org/qt-mobility/contacts/commit/44f04fea41dd2641947ae8d1ec4825f083976908
Can this fix be backported to the 1.1 branch?
