-----------------------------------------------------------------
Something is messed up with that file... it starts with a wrong startxref
value, then some bad stream lengths... it is able to recover from all that,
until it hits an object stream and doesn't survive that. PDF.js can open the
file, but gives up at page 8. A look at the file with NOTEPAD++ finds a lot
weird spaces and CRs. -No, there is no quick solution.- I tried opening with
Adobe Reader and resave it, but that brought an error. -I suspect that they
could open it because they do parse on demand and we don't, i.e. they didn't
hit the bad part immediately.- We parse the entire file. We're lenient on bad
files, but this is not always successful.
