I've had this problem (in 5.3 and 5.4) when the PDF version was too high or
when the PDF had security / was passworded. Using the right version or
removing the security always fixed that problem.
I normally use PDF version 1.4 (Acrobat 5.x) with no security but that's
not working in the new version. I just tried PDF version 1.6 (Acrobat 7.x)
which had some encryption on it. It failed on the encryption and logged the
failure. The 1.4(5x) PDFs get no mention in the log (which I have set to
0/DEBUG for the TOC so the log is showing a lot) so it doesn't appear to be
aware of failing. Now I've tried both 1.6(7x) and 1.5(6x) with no
encryption and they both fail to get and publish the title to the DMP
image's TOC.
Hmm.
