Having problems with drawing some SVG's. Can I send them to test?

[tobiasoort]

Put them online somewhere (like pastebin) and link them here.

Can You draw them?

Stream str=(this.GetType().Assembly.GetManifestResourceStream(resourceName));

              SvgDocument svgDoc = SvgDocument.Open<SvgDocument>(str, null);

                svgDoc.Draw();

Same drawing from file (src, not stream)

Problem uccurs in method:
protected virtual void Render(SvgRenderer renderer)
{
this.PushTransforms(renderer);
this.RenderChildren(renderer); //here
this.PopTransforms(renderer);
}

protected virtual void RenderChildren(SvgRenderer renderer)
{
foreach (SvgElement element in this.Children)
{
element.Render(renderer);
}
}

I have 1 element in collection (SvgUse) which cannot be drawn. Can you help me?
