Well, depending if the diagram is still vectors in the PDF, that might help you in getting the actual image out as a vectored image.
Cool, although the project clearly has a long way to go. I'll be interested to see how it's doing in about six months.

I noticed Inkscape refuses to read their example SVGs; it appears Inkscape *needs* the xmlns attribute in the <svg> tag. Without an xmlns attribute, Inkscape brings up an error dialog ("Failed to load the requested file foo.svg"), but prints nothing to stdout or stderr.
Identical symptoms are described in #1008829, #1008822. They have been closed.
I experience this issue with a CVS build from yesterday (2005-01-10), opening the files from the command line (inkscape foo.svg). Perhaps this was fixed and has been broken again?
