--- Comment #2 from Akira TAGOH <tagoh at redhat.com> ---
This seems causing by
and now "hash" object has to be available in the cache anyway otherwise the
matcher won't works as expected. due to this, FcFreeTypeQueryFace() from
firefox is failing because they give "" as a filename and fontconfig requires
the valid filename to generate "hash".

As they know what they do, it can be worked around in firefox too.

FWIW FC_FILE is in the matcher now, removing FC_FILE from the pattern (in
gfsDownloadedFcFontEntry::InitPattern at gfx/thebes/gfxPangoFonts.cpp say) may
causes unexpected result.
