I believe you've already sent this font to us -- at least I've found
it on my harddisk :-)

Well, the font *is* broken.  It can't work standalone.  Both the GSUB
and GPOS tables refer to non-existent glyphs (and BASE probably too I
suspect).  I really wonder which information of this font is valid at
all.  It is probably used as a glyph container only, and all other
information is already in the PDF.

`Fix' -- ha!  You mean we should add weird hacks to support this crap.
I basically don't object, but I fear that this means a lot of work
since we had to make FreeType synthesize the missing data (or to strip
the invalid information) to get consistent results.  Volunteers
welcome.
