I looked a bit more into my problems, and found that firefox crashes
with an assertion inside pango, if the FONTCONFIG_PATH is set (even if
it is set to the default value /etc/fonts). The assertion I run into is
that a FcPatternGetString (pattern, FC_FAMILY, 0, (FcChar8 **) &s)
returns FcResultTypeMismatch for one pattern. And in fact, if I print 
the pattern, it looks as if the family name is mistaken as a boolean:

Pattern 26 of 32
        family: FcFalse(w)
        familylang: "xx"(s)
        style: "Gothic-Regular"(s)
        stylelang: "xx"(s)
        slant: 0(i)(s)
        weight: 100(i)(s)
        width: 100(i)(s)
        size: 9.75(f)(s)
        pixelsize: 13(f)(s)
        foundry: "unknown"(s)
        antialias: FcTrue(s)
        hintstyle: 2(i)(s)
        hinting: FcFalse(w)
        verticallayout: FcFalse(s)
        autohint: FcFalse(s)
        globaladvance: FcTrue(s)
        file:
"/usr/share/fonts/japanese/TrueType/sazanami-gothic.ttf"(s)
        index: 0(i)(s)
        outline: FcTrue(s)
        scalable: FcTrue(s)
        rgba: 5(i)(s)
        charset: set(s)
        lang: aa|ast|ay|bg|bi|br|ch|da|de|en|es|eu|fj|fo|fur|fy|gd|gl|
gv|ho|ia|id|ie|io|is|it|ja|kum|lb|mg|nb|nds|nl|nn|no|oc|om|os|pt|rm|ru|
sel|sma|smj|so|sq|sv|sw|tn|ts|vo|wa|xh|yap|zu(s)
        fontversion: 65536(i)(s)
        capability: "otlayout:kana"(s)
        fontformat: "TrueType"(s)


Starting firefox without a FONTCONFIG_PATH seems to work fine.
