Attached is the patch which catch this error and throws meaningful

lisp/org-habit.el : (org-habit-parse-todo)
  - Find sr-days only if scheduled-repeat is non nil
  - Used 4th element of the list returned by (org-heading-components)
    as habit-entry
  - Modified the error message to be more meaningful.
