after installing xubuntu 12.10 alpha on my notebook, awn (avant-window-navigator) wasn’t the same again even though i dropped my .gconf directory to new installed user drive. the reason was the new config directory of awn ~/.config/desktop-agnostic.

so i found the solution at the bug report #990774:

apt-get build-dep avant-window-navigator
apt-get -b source avant-window-navigator
sudo dpkg -i *.deb

hope it works for you too!
