Need help on dvi viewer with freetype

[crusius_at_stanford . edu]

hi! right now i have a pretty functional dvi viewer written for ggi
and using freetype for fonts. sometimes, however, weird things happen,
and i hope someone can help me.

as an example, if i'm viewing a file that uses cmex10, for example:
when the dvi files uses glyph number 90, freetype signals an error.
here's what happens: the code below, executed with ch=90, and
curr_font->face being from cmex10.pfb, scaled correctly

-----------------
if(FT_Load_Glyph(curr_font->face,ch,FT_LOAD_NO_HINTING) ||
   FT_Get_Glyph(curr_font->face->glyph,curr_font->glyphs+ch))
{
  fprintf(stderr,"Could not load glyph %d from font 
%d.\n",ch,curr_font->number);
  terminate(1);
}
-----------------

terminates my program (could not load glyph 90 from font 18). i would
like to release my viewer for the public, but while these types of
errors keep popping up i can't... (btw, that never happens with cmr10
and the likes. it also works fine with other glyphs from cmex10) since
i'm no font expert, i hope some of you guys can pinpoint where the
error is occurring (in freetype, in cmex10, encoding, my code...).

thanks!
