Just to confirm Frederic's answer, the fonts.cache-2 files in
/var/cache/fontconfig are directory caches, while ~/.fonts.cache-2 is a
global cache.  The directory caches are generated by fc-cache (so
regular users can't generate them), whereas the global cache is
generated on a per-user basis to handle any missing cache information
that's no in the directory caches.

Probably a bug that I've squashed.
