Hmm, I tried looking at the librsvg source to see if I could work out
whether there's anything funny going on, but it's in rust and I don't
understand it, so that didn't help at all. I'm pretty much stumped. If
I get a chance I'll see if I can dig the Mac out and see if I can
reproduce it.

Maybe try Jim's builds:

I know SVG was working on them recently.
