--- Comment #7 from Jeremy Huddleston Sequoia <jeremyhu at freedesktop.org> ---
I nuked the fontconfig caches on my system and re-ran fc-cache -v, and the
output is puzzling.

Why is it reporting "skipping, existing cache is valid" when there was no
existing cache, and what's the deal with 'invalid cache file:
b0a71e6bf6a8a1a908413a823d76e21f-le64.cache-7' ... hmm...
