The same for me, on

GNU Emacs 24.3.1 (x86_64-pc-linux-gnu, GTK+ Version
 3.12.2) of 2014-06-06 on barber, modified by Debian

- are you sure it worked on 24.3? (I think 24.3 and
24.3.1 are the same.)

If you are using the tty, this can be solved as all of
those key issues (e.g., C-m) with the same method.
Check out these files; search for "C-[" and
"C-left-bracket". Won't work in X, of course...
