Sample code in docs for QML video element is broken

The documentation for the QML video element (http://qt-project.org/doc/qt-5.0/qtmultimedia/qml-qtmultimedia5-video.html) contains the following sample code:

import QtQuick 2.0
import QtMultimedia 5.0

Video {
id: video
width : 800
height : 600
source: "video.avi"

MouseArea {
anchors.fill: parent
onClicked:

}

focus: true
Keys.onSpacePressed: video.paused = !video.paused
Keys.onLeftPressed: video.position -= 5000
Keys.onRightPressed: video.position += 5000
}

Using this code, when you press the space bar, left arrow, and right arrow keys, the video does not seek or pause. Instead, the following errors are logged:

file:///home/kehres/Code/qmlvideo/bug_report.qml:18: Error: Cannot assign to read-only property "paused"
file:///home/kehres/Code/qmlvideo/bug_report.qml:19: Error: Cannot assign to read-only property "position"
file:///home/kehres/Code/qmlvideo/bug_report.qml:20: Error: Cannot assign to read-only property "position"

The exact steps to reproduce are:

1) Copy the above sample code into a qml file.
2) Modify the "source" property to reference a valid video file.
3) Use qmlscene to execute the qml file.
4) Click the window to start video playback.
5) Attempt to use the space bar and arrow keys to pause/seek.
