Aha, I checkout that commit again, indeed, pdf exist before. Weird, When I
revert this commit. The issue is gone. This is weird. Do you have same
problem?

Hmm, I tried to pull again, Now with the latest commit. The problem is
gone. I guess I must messed something up when I debug org-link-beautify.
Anyway, It's my fault, I have not confirmed this bug before minimal emacs
config. Sorry about that. Nicolas.
