Oops, my fix wasn't completely correct either. This one is and is less redundant although it doesn't keep with the spirit of org-set-local
(org-set-local 'buffer-substring-filters
(cons (lambda (x) (set-text-properties 0 (length x) nil x) x)
(if (boundp 'buffer-substring-filters) buffer-substring-filters nil)))
