The following code-snippet, documented at http://doc.qt.nokia.com/qtmobility-1.2/qml-fileeffect.html as the way to play a FileEffect, cannot be executed, due to undefined play() slot in the FileEffect element:

FileEffect {
     id: myFileEffect
     loaded: false
     source: "file:///myfile.ivs"
 }

 MouseArea {
     onClicked: myFileEffect.play();
 }

The slot is missing from the c++ implementation of the binding.
