[O] Unable to clock out after "undo"

[Ab Cd]

Hello,


I experienced a weird behavior with org-mode while using clocking commands.


Here are the steps to reproduce it:


* Open a new file. 

* Start a new heading (here "This is a test"). Then clock in and out (C-c C-x 
C-i C-c C-x C-o)


Now, as expected, we have the following:

------------------------------8<------------------------------
* This is a test
  CLOCK: [2012-01-05 jeu. 17:30]--[2012-01-05 jeu. 17:30] =>  0:00
------------------------------>8------------------------------

Now let's undo, with C-_

Again, as expected, we heve the following:

------------------------------8<------------------------------
* This is a test
  CLOCK: [2012-01-05 jeu. 17:30]
------------------------------>8------------------------------

So we're back to the state where a task has been started but not completed, 
right?

Let's try to clock out again (C-c C-x C-o). Now I have 'No active clock'.

It seems that it does the same thing if I close emacs and open it again. I was 
asked if I wanted to clock out before closing, tho.

Is that a bug ? Or did I miss something?

Thanks for your help.

Have a nice day.
