Looks like this problem is *not* fixed yet (CVS checkout from today):
mfabian@magellan:/usr/X11R6/lib/X11/fonts/truetype$ sudo time fc-cache -v .
fc-cache: ".": caching, 919 fonts, 0 dirs
fc-cache: succeeded

one cache file has been created. Try again:
mfabian@magellan:/usr/X11R6/lib/X11/fonts/truetype$ sudo time fc-cache -v .
fc-cache: ".": skipping, 919 fonts, 0 dirs
fc-cache: succeeded

OK, skipped now, cache is up to date.
Try to generate a cache for a different directory:
mfabian@magellan:/usr/X11R6/lib/X11/fonts$ cd ../Type1/
mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$ sudo time fc-cache -v .
fc-cache: ".": skipping, 919 fonts, 0 dirs
fc-cache: succeeded
0.00user 0.00system 0:02.02elapsed 0%CPU (0avgtext+0avgdata
0maxresident)k
0inputs+0outputs (0major+348minor)pagefaults 0swaps
mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$
Surprisingly skipped, although no cache for this directory
exists (neither in /var/cache/fontconfig nor in
/usr/X11R6/lib/X11/fonts/Type1).
No new cache file has been generated:
mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$ ls /var/cache/fontconfig/
d6867d8c7d183335b46263581b96fdc1.cache-2 stamp

Hmm, that problem seems to persist as well:
mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$ sudo time fc-cache -v /usr/X11R6/lib/X11/fonts/Type1
fc-cache: "/usr/X11R6/lib/X11/fonts/Type1": caching, 59 fonts, 0 dirs
fc-cache: succeeded

mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$
One new cache file has been generated:
mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$ ls /var/cache/fontconfig/
57fddf4aeff95a0b98650bf3f13c26fe.cache-2 stamp
d6867d8c7d183335b46263581b96fdc1.cache-2
mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$
Try again adding a '/' at the end of the path:
mfabian@magellan:/usr/X11R6/lib/X11/fonts/Type1$ sudo time fc-cache -v /usr/X11R6/lib/X11/fonts/Type1/
fc-cache: "/usr/X11R6/lib/X11/fonts/Type1/": caching, 59 fonts, 0 dirs
