This seems to be a subsetted `tricky' font.  However, all bytecode
instructions have been stripped off from the glyphs...  Of course,
this *must* fail :-)

It seems that FreeType doesn't know this tricky TTF.  Your sample font
doesn't contain any `name' table entries, and the cvt/fpgm/prep
checksums are not known to FreeType (cf. function
`tt_check_trickyness_sfnt_ids' in file `src/truetype/ttobjs.c').

Do you have the original, unstripped one?  Please send it to me
privately if possible.
