This stuff is all pushed out now, (so will be in today's 1.2.4).

Thanks for verifying things. It turns out that what the problem was
here is that svg2png was linking against an old (system-installed)
cairo rather than the shiny new cairo being tested. So the SVG was
correct, but then it was being rendered to a PNG with a buggy cairo,
(so no bug in librsvg even).

Behdad recently fixed the svg2png linking bug, so now that I looked at
your branch again everything passed just fine.

Thanks again,
