I reported this problem earlier against 7.4, it still occurs
with the latest GIT version. Maybe (probably) I'm being stupid,
if so could someone please tell me.

Tangling from an indirect buffer fails with the following stack trace:

     Debugger entered--Lisp error: (wrong-type-argument stringp nil)
       (message "tangled %d code block%s from %s" block-counter (if (= block-counter 1) "" "s") (file-name-nondirectory (buffer-file-name ...)))
       (let ((block-counter 0) (org-babel-default-header-args ...) path-collector) (mapc (lambda ... ...) (org-babel-tangle-collect-blocks lang)) (message "tangled %d code block%s from %s" block-counter (if ... "" "s") (file-name-nondirectory ...)) (when org-babel-post-tangle-hook (mapc ... path-collector)) path-collector)
       (save-excursion (let (... ... path-collector) (mapc ... ...) (message "tangled %d code block%s from %s" block-counter ... ...) (when org-babel-post-tangle-hook ...) path-collector))
       call-interactively(org-babel-tangle t nil)
       call-interactively(execute-extended-command nil nil)

The problem seems to be in this fragment of org-babel-tangle:

       (message "tangled %d code block%s from %s" block-counter
                (if (= block-counter 1) "" "s")
            (file-name-nondirectory (buffer-file-name (current-buffer))))

On an indirect buffer buffer-file-name returns nil, replacing this by:

       (message "tangled %d code block%s from %s" block-counter
                (if (= block-counter 1) "" "s")
            (file-name-nondirectory (buffer-file-name
                                     (or (buffer-base-buffer) (current-buffer)))))

seems to do the right thing.


Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See


Your bug report will be posted to the Org-mode mailing list.
