Problem with saving Visio in VSDX format



I have a problem with saving a visio files in VSDX format. I got ArgumentNullException: key cannot be null.

The code I’m using looks like this:
Diagram visio = new Diagram(“test.vsd”);
visio.Save(“test.vsdx”, SaveFileFormat.VSDX);

I’ve attached (48.2 KB) which cause this problem.
