Since I'm also interested in this and fail to get it working, please allow me to provide such an example. The svg-file is taken of the german Wikipedia-article of the svg file format. It includes fonts, I'm not sure if this causes trouble.

Note: When I include the extension in the filename (testimage.svg) I get "!LuaTeX error: cannot find image file 'm_k_i_v_testimage.pdf'" probably due to some failed conversion stuff. If I omit the .svg, I get a dummy frame in the pdf output.
