[Qt-qml] QTBUG-15191 Memory Leak with XMLListModel, how to workaround in Qt4.7.0 on Maemo

[Sudheer K.]

I developed a widget for Maemo which is dependent on XMLListModel. The widget
pulls stock quotes from Yahoo finance in regular intervals. Due to a known issue
with XMLListModel [1], there is a memory leak every time the model is reloaded.
However, I have to reload the model to get the latest quotes.

I am aware that this memory leak will be fixed in Qt 4.8.0. However, I don't
know if/when Maemo will get the Qt update. Until then, I am looking for a
workaround to avoid the memory leak. Here is a skeleton of my code[2]. Can you
give me any suggestions?
