1. Create a Qt Quick 1 Application and configure it with Qt 4.
2. Add some JavaScript to main.qml.
   I used:

   import QtQuick 1.1
   
   Rectangle {
       width: 360
       height: 360
       Text {
           text: qsTr("Hello World")
           anchors.centerIn: parent
       }
       Timer {
           interval: 2000
           repeat: true
           running: true
           onTriggered: {
               var i;
               for (i = 1; i < 2500; ++i) {
                   var j;
                   j = i * i;
                   console.log(j);
   
               }
           }
       }
   
       MouseArea {
           anchors.fill: parent
           onClicked: {
               Qt.quit();
           }
       }
   }
   

3. Build this and run it in QML Profiler.
4. On the Events tab, right click and select "Extended Event Statistics".
   The QML Profiler will in some lines display "Shortest Time" of 0.000 μ. This is inconsistent with the other data:
