QML Application crashes on Symbian^3 when XmlListModel is loading and application quit at that moment

I extended the QML Hello World application by one XmlListModel, which is loaded from internet. When you exit the application during loading of XmlListModel on Symbian^3, the app closes, but it shows a message "Application close: testApp". (where 'testApp' is the name of my application).

Works OK under Simulator (on PC), crashes on Symbian^3 with Qt 4.73 on the phone (and compiled for 4.73) and also crashes with Qt 4.74 on the phone (and compiled for 4.74).

The whole application is the default 'Hello World' application created by Qt Creator, but it has one XmlListModel added to it which loads one big .xml file from the internet:
//-----------------
XmlListModel {
source: "http://rpc.weblogs.com/changes.xml"

onStatusChanged:

{ statusText.text = "XmlListModel status " + status; // update status string in some label }

}
//-----------------

XmlListModel.source is just some random but big .xml file from internet (leaves you enough time to close the app while loading data). For whole file see attachment.
