Hi. I'm using the org included with a recent build from emacs git. I
have this tst.org:




[[name][link]]

* heading
#+NAME: name

text




I open it with 'emacs -Q'. I move the point to the link at the top, and
C-c C-o to follow the link. This doesn't work:

  Debugger entered--Lisp error: (wrong-type-argument stringp nil)
    string-match("[ \f\11\n\15\13]+" nil 0)
    split-string(nil)
    org-link-search("name" 3)
    org-link-open((link (:type "fuzzy" :path "name" :format bracket :raw-link "name" :application nil :search-option nil :begin 1 :end 15 :contents-begin 9 :contents-end 13 :post-blank 0 :parent (paragraph (:begin 1 :end 17 :contents-begin 1 :contents-end 16 :post-blank 1 :post-affiliated 1 :parent nil)))) nil)
    org-open-at-point(nil)
    funcall-interactively(org-open-at-point nil)

Apparently org doesn't like the empty line right after the #+NAME tag.
Removing that empty line makes it work.

Thanks!

Isn't the #+NAME tag used to label things below it? I think that would 
explain why it doesn't work when there's nothing directly below it.

If you want to link to the heading, perhaps you should try something 
like [[* heading][link]]?

Thanks for the report.  As suggested in Dante's reply, the blank line
following #+name is invalid syntax.

  https://orgmode.org/worg/dev/org-syntax.html#Affiliated_keywords

On maint (3bb073b63), the type error is now avoided for invalid name
keywords.  No attempt is made to match these keywords, though, so your
example won't lead to a match aside from through a fuzzy text search
when org-link-search-must-match-exact-headline is nil.

Thank you Kyle, Dante. I was using the wrong thing. I should have been
using the CUSTOM_ID property instead of the #+NAME tag. This was my
fault. I guess the fact that #+NAME was ALMOST working the way I wanted
it to increased my confusion. And the unhelpful error message.

Thanks again
