I ran the Inkscape, opened the pdf file and then "save a copy" in the eps format. As shown in the attached files, the coordinate information is missed in the converted eps file.

AFAICT a known issue in cairo 1.10.x, tracked for Inkscape in

- Bug #813886 “Save as EPS or PS incomplete with cairo >= 1.10” https://bugs.launchpad.net/inkscape/+bug/813886

In my tests the EPS file saves ok with cairo 1.8.10 and cairo 1.12.2, but misses certain parts with cairo 1.10.2, independent of which Inkscape version is used.

The information about the my computer and Inkscape is listed as follows. OS: Ubuntu 12.04 LTS amd64 Inkscape : 0.48.3.1 r9886 (Installed from the Canonical source)

Based on your provided EPS file, Inkscape was using cairo 1.10.2 to export to EPS: %%Creator: cairo 1.10.2 (http://cairographics.org)

While I tried on another machine with Inkscape 0.48.2 r9819, the conversion is perfectly done as expected.

Which version of cairo was installed on that other system?

So have I missed something to be installed? Or is there a bug for the newer version of Inkscape?

You didn't miss anything to be installed, nor is it a bug in newer Inkscape versions. The problem is with cairo 1.10.x - independent of which Inkscape version is used. Once linux distros have upgraded to the current version of cairo (1.12.x), the problem will be gone.
