QtQuick.Dialogs missing

FileDialogs 1.0
http://qt-project.org/doc/qt-5.1/qtquickdialogs/qml-qtquick-dialogs1-filedialog.html

First, I'm a Qt/QML greenhorn, I'm sorry if I missed something.

I created a Qt Quick 2 UI project and wanted to import QtQuick.Dialogs 1.0, but it complains “Module not found”.
/usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick contains all imports, expect 'Dialogs' and 'Layouts'.

I guess its a bug because the modules are shown during the import auto-completion.

import QtQuick 2.1
import QtQuick.Dialogs 1.0
Rectangle {
    width: 360
    height: 360
    Text {
        anchors.centerIn: parent
        text: "Hello World"
    }
    MouseArea {
        anchors.fill: parent
        onClicked: {
            Qt.quit();
        }
    }
}
