I have this same problem. In fact, I deactivated the plugin but a week later still having the issue. So I removed the plugin altogether but I am still getting indexing errors with google trying to index this. Please help!
Here are a couple of instances:
wp-content/plugins/ckeditor-for-wordpress/ckeditor/
wp-content/plugins/ckeditor-for-wordpress/ckeditor/skins/kama/
wp-content/plugins/ckeditor-for-wordpress/ckeditor/plugins/about/dialogs/hidpi/
