Fix a segfault when XftConfig or ~/.xftconfig contains directories with
gzip'd fonts. The next release of freetype2 will allow building with the system version of zlib, so this won't be an issue. Reported by: alane Obtained from: FreeType CVS and /usr/src/lib/libz/infcodes.c Approved by: maintainer
