    try {
        throw Gdk::PixbufError(NULL); // <---- new code
        img = Gdk::Pixbuf::create_from_file(fileName);
    }
    catch (Gdk::PixbufError e)
    {
        g_message("Gdk::PixbufError in SVGPreview::showImage");
        return;
    }

This does trigger the catcher. So the catcher works.
