This morning, I updated my packages (Options -> Manage Emacs Packages -> U
->X) and now, internal links work perfectly.

For the record, the updated packages were:

dash-20171009.105
flycheck-20171009-1145
helm-20171009.221
kaolin-theme-20171009.1130
org-20171009
org-plus-contrib-20171009
org-ref-20171009.2019
python mode-20171005.1620


I'll let you know if the error returns.
