Bug#1051683: libfontconfig1: "out of memory" errors when the working directory was deleted

[Paul Wise]

Package: libfontconfig1
Version: 2.14.2-5
Severity: minor
Usertags: warnings

When I run any program that uses fontconfig in a working directory that
doesn't exist, I get "out of memory" errors. The same thing does not
happen when the current directory does exist. The fontconfig library 
seems to work fine in both cases, so the error seems to be spurious.

The lack of a valid working directory should not affect fontconfig
anyway, because it only works on files in /etc and ~/.config AFAIK.

   $ mkdir foo ; ( cd foo ; sleep 5s ; fc-match > /dev/null ) & rmdir foo ; sleep 10s
   [1] 2359576
   Fontconfig error: "/etc/fonts/fonts.conf", line 86: out of memory
   Fontconfig error: "/etc/fonts/fonts.conf", line 91: out of memory
   Fontconfig error: Cannot load config file from /etc/fonts/fonts.conf
   [1]+  Done                    ( cd foo; sleep 5s; fc-match )
   
   $ mkdir foo ; ( cd foo ; sleep 5s ; fc-match > /dev/null ) & echo not rmdir foo ; sleep 10s
   [1] 2359806
   not rmdir foo
   [1]+  Done                    ( cd foo; sleep 5s; fc-match )
