There are other PDF viewers that are based on Poppler and such
a warning is not output. Perhaps FcInit is called in Poppler
and the xpdf issue comes from Motif (since it comes first).

If a call to FcInit wasn't required, that's an API change and
an ABI breakage in fontconfig.

That's something that they would have to solve.

If I understand correctly, the new fontconfig version was not
ready yet for Debian, and it would also require a soname bump
(when ready).
