That is fine, though I'll apply the patch. There does appear to
be another bug, or my misunderstanding. That is, even
without the link,
[[file:/home/joe/sample.pdf]]
does not work properly. That is, clicking on it (mouse 1)
opens the pdf inside emacs rather than in a standalone pdf reader.
Previously
that wasn't the case (if memory serves). Using
[[file:/home/joe/sample.pdf::1]]
for the link opens it in a standalone reader.
