This workaround is far from ideal, but you might want to try it if
everything else fails.

It turns out that several programs including Microsoft Word (at least
on the Mac), OmniGraffle, and others, produce a PDF file that does
preserve the empty line. I'm sure you will be able to find an adequate
program for Ubuntu.

If you insert such a PDF created with the external program as a figure
in your TeX document, the empty line will also be preserved in the PDF
produced by pdftex.

It's a nasty workaround but it works.
