Actually, I think this is fixed in the X.org found in 'unstable'. I
tried to find the FreeType code there. From the file, I started looking
for the source for /usr/lib/xorg/modules/fonts/libfreetype.so, which is
hw/xfree86/dixmods/ftmodule.c in xorg-server-1.0.2. But this file is
*very* short, and mostly includes a few files, among which
/usr/include/X11/fonts/fontmod.h from the libxfont-dev package. The
runtime counterpart of libxfont-dev is libxfont1 and:
% dpkg -s libxfont1
Package: libxfont1
[...]
Description: X11 font rasterisation library
libXfont provides various services for X servers, most notably font
selection and rasterisation (through external libraries).
.
More information about X.Org can be found at:
<URL:http://xorg.freedesktop.org>
<URL:http://lists.freedesktop.org/mailman/listinfo/xorg>
[...]
In our case, the "external library" is indeed /usr/lib/libfreetype.so.6:
% ldd /usr/lib/libXfont.so.1
libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x4008c000)
libz.so.1 => /usr/lib/libz.so.1 (0x400f8000)
libm.so.6 => /lib/libm.so.6 (0x4010c000)
libfontenc.so.1 => /usr/lib/libfontenc.so.1 (0x40132000)
libc.so.6 => /lib/libc.so.6 (0x40138000)
/lib/ld-linux.so.2 (0x80000000)
Therefore, everything looks fine in sid: the X server uses the
system-wide FreeType library, by way of libXfont. That explains why the
bug doesn't happen in sid even with xfontsel (for which the font
rendering is done on the *server* side, contrary to e.g. GNOME
applications, which are [most of the times indirectly] dynamically
linked to FreeType), altough the last upload of xserver-xorg-core (which
provides /usr/lib/xorg/modules/fonts/libfreetype.so) happened *after*
the first upload of FreeType 2.2.1 (which, as we suppose, is the first
version fixing the bug that hit the Debian archive).
In short: just wait until the X.org from 'unstable' reaches bpo. :-)
