 Can't type accented characters anymore: <dead-acute> is undefined:
Date: Thu, 14 Nov 2013 10:37:04 +0100

On Ubuntu, I can't type accented characters through dead-keys anymore.

$ emacs -Q
<in a scratch buffer>
type right-control quote

You get a "<dead-acute> is undefined".

This works fine with "emacs -Q -nw" and in all other applications. I
found 2 workarounds on the web:

$ XMODIFIERS='' emacs

and

typing C-x 8 RET RET once

Then, typing "right-control quote e" creates the correct é.

Many people report the same issue (just search "XMODIFIERS emacs" in
any search engine.

This is like that for both emacs24 and emacs-snapshot on at least Ubuntu
14.04 (but some users have experienced this for years). Some related
reports:
