Strange Behaviour while rescheduling date

Strange Behaviour while rescheduling date

[G. Martin Butz]

Hi,

I tried to describe this error a while ago, but did not get any response 
- probably due to the fact, that I can not find out, how to securely 
reproduce this very annoying behaviour; I will try to describe:

1. I try to reschedule an entry (C-c C-s)
2. The buffer with the org file seems to be replaced by a calendar
3. Futhermore 2 additional buffers appear with the calendar in it
4. If can not assign a date meaning cursor movement (Shift Left/Right) 
seems to be random e.g. skipping a few day and also going in the wrong 
direction (e.g. left means right)
5. If I try quitting emacs, I am asked if I want to save the original 
org-mode buffer (in which I tried to reschedule a date)
6. If I dare to do this, emacs will write the calender into this buffer 
thereby erasing the original org mode file.

I tried to deliver a backtrace (load org-mode and activate the debugger 
according to [1]) but: There is no error message at all (!sic)!

The only thing I could do is to make a screenshot showing state no. 3 [2].

This makes keeping track of dates in org-mode almost unusable for me. 
Does anyone have an idea, what I could do to pinpoint this behaviour?

I am running org-mode 8.2 (updated today, but have had this error since 
a while) on emacs 24.3.1 on Linux Crunchbang Waldorf.

Thanks for any hints and thanks alot for wonderful org-mode in general
Martin

In case I try to reschedule a date from the weekly agenda view I get the 
following backtrace; I am under the impression, that this seems not to 
be the bug, which I have tried to describe in the last message, but at 
least it shows, that something is wrong (with my setup/emacs/org?)

----------------------------8<-----------------------------------------
Debugger entered--Lisp error: (error "Before first headline at position 
1 in buffer date.org")
   signal(error ("Before first headline at position 1 in buffer date.org"))
   error("Before first headline at position %d in buffer %s" 1 #<buffer 
date.org>)
   (condition-case nil (outline-back-to-heading invisible-ok) (error 
(error "Before first headline at position %d in buffer %s" (point) 
(current-buffer))))
   org-back-to-heading(t)
(...)
----------------------------8<-----------------------------------------

(I post the full backtrace message as txt-attachment).

Thanks
Martin

Hi,

once more me - in case anyone is interested. I finally went through my 
config file step by step. The responsible lines in my .emacs were:

---------------------------8<------------------------------------
(defadvice split-window (after move-point-to-new-window activate)
   "Moves the point to the newly created window after splitting."
   (other-window 1))
---------------------------8<------------------------------------

FYI, I also experience that (annoying) message now and then, but I never
understood which conditions did make it appear -- and, no, it's not an advised
split-window in my case ;-(.

This message happens when Org tries to go back to a heading and the cursor is before the first headline.  Most of the time this should not cause an error - please make a backtrace when it happens.

well, I am not entirely sure, that the backtrace I manage to get  was 
actually directly related to the initially described behaviour. Seemed 
to be two differnt things but somehow connected. As I could not savely 
reproduce the rescheduling and replacing of an org-buffer by the 
calendar (no backtrace/no 'official' error) I did use the rescheduling 
of a date starting from the agenda buffer as a test case. This led to 
the offendig config /split-window/.

Now everything seems to work fine.

So far
Martin
