QML refer .qrc even if external ressources are used

Hello,
I just found out that qml tends to refer any kind of files via the resource system
as soon as I'm loading my qml sources via .qrc.

Here a short example:
I load a qml file via resource system into a QDeclarativeView:

this->my_qml_view->setSource(QUrl("qrc:///qml_source/main.qml"));

in main.qml I just load an Image

 

Image {
    id: example
    source: "/home/me/My Data/picture.jpg"
}

When I try to run this example I get the message:

QML Image: Cannot open: qrc:/home/me/My Data/picture.jpg

I develop on a Windows7 system and it worked fine.
Now I wanna test my application on my openSuse system and
got this kind of message.

I ask about this on the Qt developer platform and it seems
that this could be a bug.
