Hi,

I work with GNU Emacs 24.0.95.1 (x86_64-apple-darwin, NS apple-appkit-1038.36)
[installed as Emacs-pretest-24.0.95-universal-10.6.8 from
http://emacsformacosx.com/builds ] on Mac OS X 10.7.3. (The reason for Emacs 24
is because of the latest features in Gnus). The org-mode version I use is 7.8.08.

I frequently experience crashes of Emacs during various tasks (see
http://stackoverflow.com/questions/10164425/emacs-almost-random-crashes-about-2-3-times-a-day-on-mac-os-x#comment13039387_10164425
which I posted earlier today when I didn't know the cause of the crashes). By
checking Console.app, I found what I also suspected: org-mode causes the
crashes. The problem is, I don't know how to solve this problem (I'm an
enthusiastic [although maybe not really experienced] org-mode user and would
*really* like to use org-mode in the future as well).

One of the crashes happened when I wanted to compile an .Rnw (Sweave) file via
C-c C-c (so totally -- at least to me -- independent of org-mode; other crashes
happened, for example, when I wanted to put in a new event in my agenda file). For this
crash, I attach the complete report of Console.app, a brief overview is:

My complete setup of org-mode and org-contacts in .emacs is:

,----[ org-mode setup in .emacs: ]
| ;; basics
| (require 'org-install); use org-mode
| (setq org-startup-indented 1); use indentation in org mode
| (add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode)); open all .org files in org-mode
| (setq org-agenda-files
|       (list "~/org/agenda.org")); set up org agenda file
| (setq org-default-notes-file "~/org/agenda.org"); set up org notes file (stores captured events -- also use agenda.org)
| (setq org-agenda-start-on-weekday nil); start agenda view on current day

|             (make-variable-buffer-local 'yas/trigger-key)

|             (add-to-list 'org-tab-first-hook 'yas/org-very-safe-expand)
|             (define-key yas/keymap [tab] 'yas/next-field)
|             ))
`----

It seems difficult to reproduce this particular crash, but crashes due to
org-mode appear frequently in my setup (multiple times a day; see also the link
to stackoverflow where I posted a link to another user experiencing something
similar; see also
http://www.humbug.in/stackoverflow/de/abort-trap-in-org-mode-in-emacs-23-on-mac-os-10-6-6-5460602.html
[I couldn't find the original post on stackoverflow for this post]). 

Please let me know if I should try anything particular and report back the output.


Cheers,

Marius
