Bug#895614: the fontconfig error comes almost everywhere.

[Peter Nowee]

@Shirish:

I'm not sure if you are seeing the same problem as the original poster 
of this bug report, but I had the same problem you describe: The error 
`Fontconfig error: failed reading config file` appearing exactly 5 
times. I could reproduce it by running `fc-cache`.

Through the links below, I found it was caused by Debian bugs #854166 
and #866052, related to 5 packages: fonts-beng-extra, fonts-deva-extra, 
fonts-gujr-extra, fonts-guru-extra and fonts-orya-extra. (In my case, 
these fonts got installed as dependencies of tuxtype.)

After manually reorganizing /etc/fonts/conf.avail/ to match the goal 
described in #866052, the error messages disappeared.

HTH,
Peter
