Here is our research results:

We extracted base64-encoded PDF attachment from 619895_1.dxl file. After base64 decoding, we found that Acroread failed to show the decoded file.

Further research shown, that between offsets 30496 (a beginning of the last PDF object found) and 34150 (the previous offset plus a declared PDF object length) the PDF gets corrupted. The remaining binary data looks like a garbage.

PD4ML just copies the problematic DXL attachment to PDF attachment “as is”. So I am afraid, the problem is somewhere by DXL export phase on your side.

BTW: The offsets are suspiciously close to 32768 (max 16bit signed integer value). I’ll check 720553_1.dxl if it is the “magic limit” for it as well.
