[Fontconfig] font missing but which one - how to debug?

[Arkadiusz Miśkiewicz]

Hello.

Adobe flash app, run under firefox (iceweasel) is showing "missing glyph" 
characters:

http://ixion.pld-linux.org/~arekm/no-font.jpg

FC_DEBUG=2503 partial log (part just before adobe plugin started):

http://ixion.pld-linux.org/~arekm/no-font.txt

(look for prgname: "plugin-container"(s)" entries).


But it is not obvious to me how to find out which font is missing based on 
such log. Any help?

Thanks,
