QML app using QDeclarativeView asks for internet connection on maemo device

I wrote a small qml app which uses a XmlListModel filled via an xml in a qrc file. The app runs fine in the QtSimulator. When I deploy the app onto my maemo device (n900) and start it there, the device wants to open a internet connection. The whole app has no reference to the internet. The xml does not even reference a schema

As soon as I connect the device to the internet the applications runs fine.

It seems to that somehow the QNetworkAccessManager makes the device think it needs an internet connection.

I have attached a small example that illustrates the issue:

It is a simple example using a ListView with a simple ListModel and another ListView with a XmlListModel.

The behaviour is like that: In both cases the n900 asks for an internet connection. But only when using the simple ListModel, actual data is displayed.

Case A: Using the XmlListModel
1) the connection window pops up
2) Me cancels the connection dialog
3) the application does not display anything

Case B: Using the simple ListModel:
1) the connection window pops up
2) Me cancels the connection dialog
3) the application displays the data
