Transparency is lost when saving as PDF

When saving a Visio drawing as PDF (or any other format). Tansparency of the shpes is lost.
See example visio file in VisioTrans.zip and generated output in visio_out.pdf.

Example code:
Diagram visio = new Diagram(basepath + “VisioTrans.VSD”);
visio.Save(basepath + “visio_out.pdf”, SaveFileFormat.PDF);

Is there a solution for this?
