Ubuntu :: XeTeX Segfaults With Custom Fonts

I installed the Adobe Font Forge fonts. They're all OpenType fonts and reside in ~/.fonts. Since around the time when I was fiddling with them, XeTeX started segfaulting whenever I used one of them. Any other font works fine. The strange thing is that I had one font already in ~/.fonts before I installed all of the new ones, which did work fine, but which now causes a segfault. The LaTeX file looks like this:

[Code]...

end{document} When I run xelatex test.tex, it segfaults and produces the log file I've attached to this post (renamed to test.txt from test.log). But, when I run xelatex with the -no-pdf switch, it produces a file test.xdv without complaining. When I then run xdvipdfmx -vv test.xdv, it segfaults and outputs to stdout what I've attached as a file error.txt. I suspect it might have something to do with system font settings that may have been changed by Fontmatrix while I was browsing my fonts, perhaps doing something that I didn't understand and messed things up. But I don't know which settings/config files/etc that may have been affected.
