PDF Version at the top is 1.6.
CFM is /V3
EBX_ENCRYPTIONTYPE is 5.
V is 4.

Note that I have other pdfs with those settings that convert fine without the code change. The difference appears to be that the ones that don't convert without the change have a LENGTH parameter of 64 set in the block at the end of the pdf, whilst the ones that do have no LENGTH parameter at all.
Might be a new problem - without further investigation it isn't possible to tell more.
