BUG: Clocking deeply nested tasks

[Bernt Hansen <bernt@norang.ca>]

Hi Carsten,

I ran into another bug a few minutes ago.

,----[ test.org ]
| #+STARTUP: odd
| * Task1
| *** Task2
| ***** Task3
| ******* Task4
| ********* Task5
| *********** Task6
| 	    :CLOCK:
| 	    CLOCK: [2008-02-27 Wed 14:30]--[2008-02-27 Wed 14:44] =>  0:14
| 	    :END:
`----

,----[ minimal.emacs ]
| (setq org-use-fast-todo-selection t)
| (setq inhibit-splash-screen t)
| (global-font-lock-mode t)
| (add-to-list 'load-path (expand-file-name "~/git/org-mode"))
| (add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
| (require 'org-install)
| (define-key global-map "\C-ca" 'org-agenda)
| (custom-set-variables
|  '(org-agenda-files (quote ("~/org/test.org"))))
`----

Key strokes:

| Key                    | Notes                   |
|------------------------+-------------------------|
| C-x C-f ~/org/test.org | Open org file           |
| C-c C-a                | Expand everything       |
| C-c C-x C-d            | Clock summaries by task |

This gives the error

org-put-clock-overlay: Wrong type argument: wholenump, -1

If I use odd even levels I can get many more nested levels before
triggering this problem so it seems to be related to the number of stars
in the tasks.  With #+STARTUP: oddeven it works for

********* TaskN (9 stars)

but

********** Task N (10 stars)

fails.
