SVG images do not show properly

Displaying attached svg - except extraShock.svg, that is OK - files do not appear properly - even though all files are displayed OK in e.g. Chrome, Firefox, IE browsers...

In QML, only black thing is visible - see "svg problem.png" attached

They are show in this form as well as attachment...

Relevant QML code snippet:

Item {
property alias source : originalImage.source

Image

{ id: originalImage anchors.fill: parent sourceSize.width: parent.width sourceSize.height: parent.height antialiasing: true }

}
