A passing remark that I made on the cairo mailing list plus some off-list discussion with Hazen has lead to the resolution of the "missing" text problem for svgcairo results. It turns out the problem is in the SVG viewer I was using (the ImageMagick "display" command), and not our cairo.c or the SVG backend to libcairo. All other viewers I have tried including iceweasel (firefox) and konqueror on Debian testing have no problems displaying the SVG results produced by svgcairo and similar results were found by one cairo list guy who did even more extensive tests. Furthermore, those SVG results validate at http://validator.w3.org/#validate-by-upload. Finally, it turns out there is a maintenance issue with Debian's version of ImageMagick (6.2.4) which is roughly two years out of date. (I assume this ImageMagick problem has propagated to Ubuntu as well.) When I downloaded, configured (which found the librsvg library to render SVG), and built the latest version (6.3.7) of ImageMagick it rendered text from our svgcairo results with no issues.
Hazen tells me there is still a text rendering problem for firefox on the Mac OS X platform when viewing our svgcairo results, but I suspect that may be an older version of firefox than the Debian testing version which works. In sum, I believe you should encounter no problems rendering our svgcairo results if you use up-to-date SVG viewers. Accordingly, I have changed our build system so it defaults to building svgcairo.
