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.
