JSVGCanvas as JTree nodes

Hi,
I try to display SVGs as JTree nodes. Therefore I wrote a TreeRenderer like
this:

public class SVGTreeRenderer extends JSVGCanvas implements TreeCellRenderer
{

  public SVGTreeRenderer() {
    File f = new File("d:\\img1.svg");
    try {
      this.setURI(f.toURL().toString());
    } catch (Exception ex) {
      //...
    }
  }
  public Component getTreeCellRendererComponent(JTree tree, ...) {
    return this;
  }
}

Running this Code I get the following Exception:

java.awt.geom.NoninvertibleTransformException: Determinant is 0

At the end, there are no SVGs displayed in the JTree. Does anyone has a
solution for this problem?

cheers,

Thomas
