Hi,

is there a way to debug what is happening after pressing some key
combination. 

I have the problem that in the agenda view when I press M-+ to run the
function org-agenda-do-date-late, sometimes (and this is the problme: it
happens randomly, not always), emacs gets freezed and I have to press
C-g to cancel. Interestingly when I press C-g I see the date on the
right side updated and everything continues working OK...

Many thanks in advance!

(setq debug-on-quit t)

You will get backtraces every time that you press C-g even for unrelated
reasons (you can just press q in the backtrace buffer to continue), but at least
you'll get one also when the problem happens.

I assume that "emacs freezes" means that it is using lots of CPU (which
you can test independently by using "top" on linux, or something similar
on other OSes).

thanks. I will try it.

yes, high CPU consumption, no response of emacs, etc.

If I try to reproduce the error, I get this message:

Debugger entered--Lisp error: (quit)

Thanks -- can't reproduce this... but make sure to tell us what
version of Org and Emacs you are using

M-x org-version RET
M-x emacs-version RET

Does it happen when you have filtered the agenda? If so, then I can
confirm this bug... 

I am using...

 - emacs 24.3.1
 - org 8.2.5h

...on...

Linux box 3.13.5-1-ARCH #1 SMP PREEMPT Sun Feb 23 00:10:07 CET 2014 i686 GNU/Linux

Emacs freezes as you describe when whenever I attempt to reschedule an
item in a *filtered* agenda that has invisible lines between it and the
next visible agenda item. This is the crucial condition: there must be
invisible text in the agenda buffer immediately following the agenda
item being rescheduled. Take the following agenda:

--8<---------------cut here---------------start------------->8---
Day-agenda (W09):
Sunday      2 March 2014
  inbox:      Scheduled:  Call Jack                                      :phone:
  inbox:      Scheduled:  Call Jill                                      :phone:
  inbox:      Scheduled:  Run up a hill                                :errands:
  inbox:      Scheduled:  Call the hospital                              :phone:
--8<---------------cut here---------------end--------------->8---

So long as the agenda is unfiltered, then org-agenda-do-date-later works
fine.

If I filter the agenda by the tag "phone"... 

--8<---------------cut here---------------start------------->8---
Day-agenda (W09):
Sunday      2 March 2014
  inbox:      Scheduled:  Call Jack                                      :phone:
  inbox:      Scheduled:  Call Jill                                      :phone:
  inbox:      Scheduled:  Call the hospital                              :phone:
--8<---------------cut here---------------end--------------->8---

...then org-agenda-do-date-later causes Emacs to go into an infinite
loop on "Call Jill" but *not* on the other phone items. This is because
of the invisible "Run up a hill" that comes after "Call Jill."

I have tested this several times with emacs -Q and can replicate it each
time.

I previously documented the issue in this thread:

AFAICT, there is something of a ping-pong game going on between multiple
bugs whose solutions conflict with each other. 

1. The bug was first introduced with the following commit:

--8<---------------cut here---------------start------------->8---
commit fafb5f3429c41cba1eddb9fc78d9f9e0980acbe2
Author: Bastien Guerry <bzg@altern.org>
Date:   Mon Feb 11 14:56:38 2013 +0100

    org-agenda.el: Fix bug when displaying a temporary overlay
    
    * org-agenda.el (org-agenda-schedule, org-agenda-deadline):
    Cosmetic changes.
    (org-agenda-show-new-time): Fix bug when displaying a
    temporary overlay with the scheduled/deadline information.
    
    Thanks to Thomas Morgan for reporting this bug and testing the patch.
--8<---------------cut here---------------end--------------->8---

...which was a response to the following bug...

http://article.gmane.org/gmane.emacs.orgmode/65538/match=agenda

2. The bug was solved by the following patch.

--8<---------------cut here---------------start------------->8---
commit 7f9d0688d47140bcac7bea627474802adfce31ee
Author: Carsten Dominik <carsten.dominik@gmail.com>
Date:   Sat Aug 31 15:44:34 2013 +0200

    Fix cursor movement to a specific column
    
    * lisp/org-compat.el (org-move-to-column): Turn off invisibility stuff
    for moving the cursor to a column.
    
    Pathc by Nick Docks
--8<---------------cut here---------------end--------------->8---

3. However, the problem resurfaced with the following patch, which
effectively reversed the previous fix.

--8<---------------cut here---------------start------------->8---
commit 2911965bfef9072a3031d48dfe2ea50bcb3ff9df
Author: Bastien Guerry <bzg@altern.org>
Date:   Wed Nov 6 09:59:46 2013 +0100

    org-agenda: Fix bug when showing the new time
    
    * org-agenda.el (org-agenda-show-new-time): Ignore invisible
    text when inserting the new time as a text property.
    
    * org-compat.el (org-move-to-column): New argument
    `ignore-invisible' to turn on `buffer-invisibility-spec'.
    
    Thanks to Marcin Borkowski and Karl Voit for reporting this.
--8<---------------cut here---------------end--------------->8---

The timing of the patch leads me to believe that it was a solution to
the problems outlined in this thread. 

- http://comments.gmane.org/gmane.emacs.orgmode/69934

So, in summary, it seems we have different bugs whose solutions have
thus far conflicted with each other.

Yes -- and I recently removed the fix I sent to Michael about S-RET
not aligning properly in table because of this ping pong.  I'll
revisit this thoroughly and hopefully come up with a stable solution,
but the problems here are closely tangled together.

Thanks for pointing at this,

The only minor issue with the fix is that move-beginning-of-line (lines
9195-6 of org-agenda.el) is slower than beginning-of-line. It's not so
bad when you push an item one day forward, but it creates significant
lag when calling org-agenda-do-date-late several times in a row.
