Hi, I sent this patch 1 month ago but it wasn't included in org. I still need it for link following to work, otherwise I get:

Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  string-match("^id:" nil)
  org-open-at-point(nil)
  call-interactively(org-open-at-point nil nil)
  command-execute(org-open-at-point)


  I remember seeing another bug report on this list providing the same solution.

Thanks.
