That explains! I've stopped using ImageMagick all together.
So it sounds to me like there is some issue in debian/ubuntu/...'s
ImageMagick packaging, probably its build config disables some
aspect of SVG --> PDF support for security concerns (???).
I'm not sure at all.
I think it has nothing to do with XeLaTeX font discovery and I don't
see any reason to apply 5/11, at least for the time being.
My suggestion would be to give up ImageMagick and install Inkscape
instead. It is provided as a deb package for debian and its derivatives.
Thanks, Akira
