I tried to reproduce this, but can't.  I tested org-mode master using
Emacs 24.4, 24.5, 25.1, 25.2, 25.3, and 26.1, and the only difference I
find is that in Emacs 24.x an external viewer (gv) is used instead of
Emacs' DocView mode.

Your Org version, master (which is three commits ahead of your
version), maint, and the bundled versions (9.1.9 for Emacs 26.1, 8.2.10
for the others) behave the same.

Do you have any information in the *Messages* buffer which might help?

Best regards
Robert
