[poppler] pdftoppm 0.86.1 / pdftoppm: Syntax Error: Expected the optional content group list

[Jim Wigginton]

If the PDF is syntactically broken then maybe the error message could be
tweaked? "*Expected the optional content group list, but wasn't able to
find it*" makes it sound as if the content group list is required and
optional is used as an adjective? Either the content group list shouldn't
be expected or it's optional.
