strange-adobe-pdf.pdf: PDF document, version 1.7

Then the version 1.7 of PDF is not (yet?) compliant with some open source application?

For now, none of the Fedora software can open this file.

I have try to use Evince, Okular, xournal, LibreOffice, Gimp, calibre, inkscape, firefox, and some other O.S. apps but none open this file

Only FoxitReader and Acrobat on windows open that file, but this software is Close Source and cannot use on My Linux.

Someone have some suggest?

Many thanks
