Both 4.62 & 4.63 suffer from another problem, perhaps limited to XEmacs.
In org-agenda-mode org-set-local is called like this:
(org-set-local 'buffer-substring-filters
(cons (lambda (x) (set-text-properties 0 (length x) nil x) x)
buffer-substring-filters))
Unfortunately, buffer-substring-filters is evaluated before it is created resulting in an error.
I've patched my version temporarily like this (which is a bit redundant):
;; Make sure properties are removed when copying text
(make-local-variable 'buffer-substring-filters)
(org-set-local 'buffer-substring-filters
(cons (lambda (x) (set-text-properties 0 (length x) nil x) x)
buffer-substring-filters))
Thanks,
Ed
