[Orgmode] Problem when customizing TODO sequence

[Jonathan Underwood]

Hi,

In my .emacs, I have this:

(setq org-todo-keywords
     '((sequence "TODO" "IN-PROGRESS" "|" "DONE" "CANCELLED")))

and when I pressC-c C-t I get this:

Debugger entered--Lisp error: (wrong-type-argument integerp sequence)
 org-todo(nil)
 call-interactively(org-todo)

This is with GNU Emacs 22 and org-mode 4.77.

Am I doing something stupid, or is this a bug?

Jonathan
