Exportation problem in Nxt Image editor

Hello, 

I have a bug with the file attached:  when I want to export the render to casual image format, a dialog box appears to tell that it will close.

I retried to render it in rhino and to export it again with Nxt editor, and I have the same problem.

So I'm asking me if it's the design in rhino which can't work in Nxt editor...

Can you try it, please?

Thanks.
