empty todo item at EOF and clock

Small bug, when clocking in and out (git head from 03.11.2008 11:15)

Adding empty TODO item at end of an org file (no heading, no text) and 
clocking in by changing TODO-state to 'STARTING' and then clock out by 
changing the items state to 'DONE' triggers an error.


My org setup is (setq debug-on-error t) and:

;; Think I have this from the manual:

(defun sr-org-todo-toggle-to-started()
   "Start the clock, if the state of a todo item changes to 'STARTED'."
   (if(string= "STARTED" state)
       (org-clock-in)))

(setq org-after-todo-state-change-hook (quote (org-clock-out-if-current 
sr-org-todo-toggle-to-started))




To reproduce this bug, move to the end of file, hit

M-S-RET

To insert an TODO item

Don't add any text, not even a heading

Toggle it to 'STARTED' using S-RIGHT

Repeat, to toggle to 'DONE'


Debugger entered--Lisp error: (error "Clock start time is gone")
   signal(error ("Clock start time is gone"))
   error("Clock start time is gone")
   byte-code("....")
   org-clock-out()
   org-clock-out-if-current()
   run-hooks(org-after-todo-state-change-hook)
   byte-code("......")
   org-todo(right)
   call-interactively(org-todo)
   org-shiftright()
   call-interactively(org-shiftright nil nil)


The item gets malformed after toggling to 'DONE' like this:


* DONE CLOCK: [2008-03-18 Di 03:10]
   CLOSED: [2008-03-18 Di 03:11]

Should be

* DONE
   CLOSED: [2008-03-18 Di 03:11]
   CLOCK: [2008-03-18 Di 03:10]--[2008-03-18 Di 03:11] =>  0:01




Only in case the item is empty and at end of file, the :CLOCK is 
considered the heading. It's really a edge case :-)


Regards,

    Sebastian
