I can open attachment 155311 [details] PDF (19 pages) in Windows 7 with Master PDF Editor, PDF-Xchange and Adobe Reader. Maybe you attached the wrong PDF.

But I do repro in Windows with attachment 155437 [details] ODP, same the error when opening exported PDF with Adobe 2011 or Adobe 2019. Repro LO 6.1.0 and master 6.4+. So there's the bug.
But document opens with Master PDF Editor, PDF-Xchange. So I change the title.

No repro with LO 6.0 so I put regression. Bug 127217 and bug 127493 start from LO 6.3 in bug 113448, so not likely the same. 
Technically one can print to PDF so there's a workarund. But there's a number of bugs related to Adobe Reader, so they deserve to be looked at.
Comment 7 bagus 2019-11-01 08:06:44 UTC
Yes. Unfortunately, most windows users uses adobe as pdf reader. 
First attached pdf file is also wrong. Used the second odp file to generate pdf.
Comment 8 Aron Budea 2020-02-02 07:39:43 UTC
Issue started with the following commit. Let's assume this isn't a regression, but certain part of the export code isn't compatible with PDF 1.5 (or an incompatibility in Adobe Reader, but I'm guessing the former).

I also cut down the file to the problematic part, it seems that an embedded PDF is causing the problem.

Change default PDF version to 1.5

Minimal sample

Note that this isn't the only embedded PDF from the presentation that causes a problem after export (and not all embedded PDFs cause an error in Adobe Reader), so a fix should be double-checked against the original.

This got fixed sometimes after, and is now fine in LO (12e8d57e791bb1befc0716d4d02af7d1d1ccb4ae) / Windows.
I'm assuming this isn't a duplicate in bug 119880.

Reverse bibisecting points to the following fixing commit.
