I can not comment on the code, but I confirm this patch fixes the issue
for DejaVu fonts. However I’m having a similar issues with oriya.ttf
font from http://www.indlinux.org/downloads/files/indic-otf-0.2.tar.gz:

$ FT2_DEBUG="any:2" ftview -m ଅ 100 oriya.ttf

Gives the same error, but I can’t ttx the font so it might be broken.
