There is a bug in checklist handling.  The following list will show the problem.

    2. [ ] Threat Model
    3. [ ] ITI Wiki
    4. [ ] Maynard stuff
    5. [ ] Annual Transition
      - wiki changes
      - ftp changes

Context:

Org-mode version 7.9.3a (release_7.9.3a @ /home/hornrj/.emacs.d/src/org-mode/lisp/)

Git commit 4cac751536e9e75f822fae18d75de6df694c8f6f

GNU Emacs 24.2.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.10) of 2012-11-08 on lakoocha, modified by Debian

How to reproduce:

If you go to the first line in the list of check boxes, line "Use Cases", and use "C-u C-u C-c C-c", it will set all of the checkboxes in the list to partial "[-]".  If you try it again you get the error "user-error: Cannot toggle this checkbox (uncheccked subitems?)".  If the checkbox has an "[X]" for complete, "C-u C-u C-c C-c" will also set the entire list to partial.

This only occurs for the first item on a checkbox list.  "C-u C-u C-c C-c" behaves properly for all the other items.

I suspect a context confusion, since the bulk change to "[-]" also changes the indent level for the two non-checkbox items in the list below item 5.
