Description:
"This PDF file is encrypted and cannot be opened."
Only the wording is printed and the PDF content is not visible.
If I drag & drop the pdf file on LibreOfficeDraw, only the first page will be output.

in a particular situation
C:\Program Files\LibreOffice\share\xpdfimport\xpdfimport_err.pdf
I think the file of the path will open, but I don't know exactly.

If I play PC Formats with the same issue, it works fine, but I can't find the cause.

I've checked in 7.6.3.1, 6.0.7.3, 7.5.8.2 and portable versions, but they don't open the same.


Steps to Reproduce:
1.PDF file open
2.
3.

Actual Results:
"This PDF file is encrypted and cannot be opened."
Only the wording is printed and the PDF content is not visible.

Expected Results:
Acrobat Reader, Foxit PDF Reader


Reproducible: Always
