Hi
my emacs is crashing quite regularly when I am using org-babel. Is
there a way to get a traceback or something similar which I could
submit to get an idea what is causing it?
I think this has probably nothing to do with org-babel. More likely,
you are using org-indent-mode, on an Emacs version where it does not
work. Check the Org manual for the exact version of Emacs you need.
I was bitten by this same bug. I narrowed it down to org-indent,
but I
had no idea I should look in the manual to see which version of emacs
org-indent was compatible with.
Here's a patch that will make emacs display an error if org-indent is
loaded with an incompatible version of emacs:

Perhaps this would be better as a separate function:
--8<---------------cut here---------------start------------->8---
(defun org-version-check (version feature level)
(destructuring-bind (rmaj rmin rbld)
(mapcar 'string-to-number (split-string version "[.]"))
(destructuring-bind (maj min bld)
(mapcar 'string-to-number (split-string emacs-version "[.]"))
(let ((msg (format "Emacs %s or greater is recommended for %s"
version
feature)))
(when (< maj rmaj)
(display-warning 'org msg level))
(when (= maj rmaj)
(unless (>= min rmin)
(display-warning 'org msg level)))
(when (and (= maj rmaj)
(= min rmin))
(unless (>= bld rbld)
(display-warning 'org msg level)))))))
--8<---------------cut here---------------end--------------->8---
It could then be called with:
(org-version-check "23.1.50" "org-indent" :warning)
I made it display a warning because org-indent seems to work almost
perfectly with the version of emacs I'm running (23.1.1).

Jason
