Why the delegate component is eating up my memory

pingal

I've created a panel to view users information everytime a user connects. I've noticed that memory leakage occurs everytime a user disconnects so I debugged the whole c++ code to find out what is causing the memory leak. And now I figured out that QML delegate portion is the causing the leak.

Here is my delegate:

I've created a delegate like below.

Component {
        id: itemDelegate
        Row {
           ..
            Rectangle {
                ...
                Text {
                    id: name
                    text: modelData.name
                }
                MouseArea {
                    anchors.fill: parent
                    onClicked: list.currentIndex = index
                }
            }
        }
}

If I replace the Component with Item, leakage stops but then I'm unable to use the above as a delegate.

Here is the simplified form of my ListView

 ListView {     
             id: list     
             model: Wrapper.mypersons
             delegate: itemDelegate     
             highlight: Rectangle {..}     
         }

Every time a user info is shown, my memory consumption increase by some ~3-4MBs but when the user is removed from the view, the memory doesn't rollback.

Any help would be appreciated.
