Sorry for not having answered before.

I asked about naming because I had installed a previous version and it
worked fine and the only thing I did for the new release was changing
the TTF name. The previous version is affected by the same kind of
problem. Since I have the Fontforge source, I investigated further.

Checking all tables with spot tool from the Adobe Font Development Kit
for OpenType, all is well, excepting the GPOS table, that makes spot crash.

It is a font of mine that mixes glyphs released under different licenses
(GPL & OFL), whose copyleft provisions render them incompatible with
each other. So I'm not allowed to distribute the font until one of them
is dual-licensed (or a newer OFL version allows this).

I realized that I get the same result removing all characters in the
Greek and Greek extended panes from the actual Junicode font. You cand
download the FontForge source at http://ousia.f2o.org/juni.sfd.bz2 and
the OpenType font at http://ousia.f2o.org/juni.sfd.bz2.

I'm afraid it might be a bug in FontForge.

Thanks for your help and sorry for the delayed answer,
