I see the same crashes Frederic sees with the same backtrace.
I can easily reproduce it like this (as root):

セグメンテーション違反です (core dumped)
root@magellan:~#
I.e. when running "fc-cache -v" the second time, it dumps core.
Of course the magic numbers in the cache files are correct already,
they are all 0xFC02FC03 (latest CVS).
Note that during the second run of "fc-cache -v" it always writes
"caching" instead of "skipping" to standard output. I.e. it doesn't
seem to notice that the cache files are already up-to-date.
