CKEditor doesn't load when using Bootstrap theme
Solved.  The I am using the development version of jQuery_update which provides a fallback version of jQuery to use on administrative pages.  -- https://drupal.org/node/1524944
It determines whether or not to use the admin version based on if the current_path() is found in the return value of path_get_admin_paths().  Unfortunately for me,  node/add is an administrative path. So, jquery_update kicks in and loads jQuery 1.5.2 to be compatible with the administrative task. It seems CKEditor can't operate with 1.5.2. I noted above that CKEditor loaded without issue for a comment field on a node. Since viewing a node isn't an administrative path, the page was allowed to load jQuery 1.10 which works fine with CKEditor.
For now, I added an array of paths to exempt from admin status (node/add, node/add/post, etc) and added that to the evaluation in jQuery_update. Content creation pages now load jQuery 1.10 and CKEditor appears normally.
UPDATE: in place of the array of exempt paths, I have put in place the patch posted by muschpusch at https://drupal.org/node/2141205 . It has solved this issue.
