The Devuan (Dng at lists.dyne.org) developer list today contains several
reports that recent system updates to libpoppler have broken PDF
processing of many documents, in multiple viewers, including okular,
evince, and xpdf.  The symptom is blank pages and/or missing font
characters.

There are two postings at

	https://bugs.debian.org/886798
	https://bugs.debian.org/890826

They suggest that a recent libpoppler security `fix' is itself broken.

Thus, we need to watch for new libpoppler source updates that really
fix the problem, and incorporate those into the TeX Live 2018 source
tree.  Alternatively, if that does not happen soon enough,
backtracking to an older less buggy version of the library may be
called for.
