Illustrator: saving as SVG gives an empty file

When I save an artboard as SVG, I get an empty file. I made sure there are no objects outside the artboard in the same layer.

When I paste the shape in the newly created SVG from the source AI file, save it and open it again I get the image below.

I guess browsers don't care about where the artboard is, since it's displayed well in my browser. But it is a pain to do these extra steps. Is there a solution for this, or what am I doing wrong here?
