--- Comment #1 from Thomas Freitag <Thomas.Freitag at alfa.de> ---
It seems as if an application without knowledge of Linearized PDF (s. spec,
annex F) has modified the PDF without modifying the linearized document
structure.
If poppler detects that it is a linearized PDF it uses this document structure
as far as possible for a faster page success but without scanning the complete
linearized document structure first. Just if it cannot detect the page using
the hint tables it falls back to the catalog dir tree.
In this case page 1 and 2 are correct in the linearized structure, page 3
points to page 4 in the linearized structure and from page 4 on it fails to get
the pages and uses the catalog dir tree, s. attached output from pdftoppm. If I
mark the PDF as not linearized or if I save it again with acrobat professional
I get the expected output again!
