I can confirm this bug (pt-BR locale). The `XMODIFIERS=''` workaround works, but the `(require 'iso-transl)` workaround does not (it allows me to type accented characters, like ã, but do not allow me to type ~, for example).
The bug appeared after I upgraded from 13.04 to 13.10.
The bug happens and the solution works even when running emacs -Q, so this is probably not related to personalization.
