Installed today ibus on ubuntu 11.10 and had this problem. Dead keys where not working. I had to do the following workaround to the problem:
apt-get install ibus-xkbc
sudo emacs /usr/lib/ibus-xkbc/ibus-setup-xkbc
Changed "python2.6" to "python2.7".
sudo /usr/lib/ibus-xkbc/ibus-setup-xkbc -> Sorry was wrnong
Select my layout where possible.
Add ibus-xkbc input method and select it.
