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.

Can you valgrind it?
