[Fontconfig] Crash with latest CVS

[Frederic Crozat]

Hi,

I'm seeing crash with CVS HEAD (it has been introduced between 20051130
and 20051205) when fontconfig is trying to parse 10-fonts-persian.conf
file. I'm building fontconfig with libxml2 support. Problem doesn't
occur when building with expat.

Backtrace :

Program received signal SIGSEGV, Segmentation fault.
