Thank you, with todays CVS fccat starts printing the contents of
~/.fonts.cache correctly now, but it crashes before finishing:

    mfabian at magellan:~$ fc-cat ~/.fonts.cache-2
    [...]
    fc-cat: printing global cache contents for dir /usr/X11R6/lib/X11/fonts/CID/Adobe-CNS1/CIDFont

    mfabian at magellan:~$ 

And "xfd -fa" still crashes for all fonts afterwards:

    mfabian at magellan:~$ xfd -fa "sans"
    Warning: Cannot convert string "sans" to type XftFont
    Segmentation fault (core dumped)
    mfabian at magellan:~$ 

(I deleted all global caches in /var/cache/fontconfig for testing,
then created ~/.fonts.cache-2 from scratch by deleting it and
then calling "fc-match sans".
