[XeTeX] problem with a font

[Pablo Rodríguez]

Using a the Army font (http://www.dafont.com/army.font) with the
xdvipdfmx contained in TL 2007 gives me the following error message:

DVI Comment:  XeTeX output 2008.04.30:1718
a.xdv -> a.pdf
<AGL:texglyphlist.txt>[1<Army(Army:Regular)@9.96pt<NATIVE-FONTMAP:Army/H>
fontmap: Army/H -> /usr/share/fonts/drakfont/otf/Army.ttf(Identity-H)

pdf_font>> Input encoding "Identity-H" requires at least 2 bytes.
pdf_font>> The -m <00> option will be assumed for
"/usr/share/fonts/drakfont/otf/Army.ttf".

** ERROR ** sfnt: Freetype failure...

FreeType is 2.3.5. I remember that I was able to use this font with
previous versions of xdvipdfmx (and xetex). Is this a bug in xdvipdfmx?
If so, has it been fixed in the devel version?

And another question: is there a command to make an object completely
transparent without having to specify the color? I'm thinking of a text.

Thanks for your help,


Pablo
