The problem is in renderSubtreeToImage() (SVGRenderSupport.cpp). We set the
paintInfo.rect to en empty IntRect.

    RenderObject::PaintInfo info(image->context(), IntRect(),
PaintPhaseForeground, 0, 0, 0);

This causes problems in RenderSVGText::paint(). RenderSVGText::paint() calls

    RenderBlock::paint(pi, 0, 0);

and RenderBlock::paint intersects visibleOverflowRect() with paintInfo.rect and
returns if this intersection is empty. But even disabling the return for
testing didn't solve the problem. I had to add the paintInfo.rect of the
SVGResource and the renderer with the relation to this resource to
renderSubtreeToImage() manually to get texts working. Sounds a bit complicated
atm :-P
