Hi!
I use org-mode quite a lot of most things and also have a number of
"workflows" in my setup, use columnview quite a lot, and also have the
habit of entering whatever text I need to write to resolve an issue
under the item in org-mode format (quite convenient, then I can just
export the subtree and send it as mail).
I have frequently run up against the issue that when trying to generate
a column view for a file, it aborts with a strange error. Since this has
become more frequent lately, I decided to resolve it.
It turns out that if you have something that looks like this:
* Top level
** TODO something
*** Proposal
Blabla
*** Submitted
Some more blaha.
and you have "SUBMITTED" as one of your todo keywords, this line will be
interpreted as an item with a keyword but no headline. Since a lot of
code assumes that there is always a headline, many functions can get a
"nil" as a headline, failing miserably.
I solved this issue by requiring that there should always be a headline
text (this is after all an assumption made in the code) and rewrote the
org-complex-heading-regexp accordingly.
Patch is attached.
Just my few cents,
Mats Kindahl

Subject: [PATCH] Resolved regexp ambiguity for item headers
X-IMAPbase: 1347255850 2
Status: O

* lisp/org.el (org-complex-heading-regexp): Resolve ambiguity in heading regexp
in favor of keywordless headline
When a simple headline is provided that just contain a todo keyword, the
regular expression will match so that the heading is treated as containing just
a keyword and no headline. Since org-column-compact-links only accept a
headline text (and not nil), this causes problems with called from
org-columns-cleanup-item. This occurs if a 'columnview' dynamic block is used
to capture a column view.
This patch solves the problem by re-writing the org-complex-heading-regexp to
require a headline text instead of allowing it to be optional. This means that
items containing only a single word that also happens to be a todo keyword is
interpreted as a headline with no todo keyword and just a headline text.
