libfo is part of (gets statically linked into as far as I understand)
the xmlroff package. So I'd suggest asking the xmlroff maintainer(s)
(the Debian XML/SGML Group, which I put into Cc:).

xmlroff has the same package version 0.6.2-1.3 in both jessie and
stretch, so one would reasonably expect for that package to behave
similarily in both stretch and jessie. So the problem you found above
looks like a regression. Maybe Gnome in stretch has seen some changes
that makes xmlroff not find the corresponding parts of gnome any more
during runtime. Anyway, if that would be the case, then that dependency
should be somehow visible in the Depends:/Recommends:/Suggests: of the
package, which, as far as I can see, is not the case.

So again I'd suggest to either file a bug report against xmlroff or to
talk to the maintainer.

It needs to be said that I have not studied the xmlroff docu - that is -
maybe there's some finesse on how the executable should be called that
could resolve the problem.

Greets,
