When I try to export attached file (contains 1 arrow shape) to SVG (File => Save As => Scalable Vector Graphics) Visio shows this error message:

Checked this with Visio 2007 SP2, Visio 2003 SP3
I believe this is some issue to be fixed..? Please can somebody confirm..?
NB: If I save this drawing as VDX, and the re-open this VDX file, the issue is gone.
Kind regards, Nikolay.
