Thank you Raymond Toy! tests/ChangeLog addition: 2011-02-24 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el (substring-no-properties): Make sure this function checks its arguments' types, the absence of which was revealed by Raymond Toy's bug report of http://mid.gmane.org/4D65D413.5050103@gmail.com .
