Well as it just salir Cinnamon 1.3.1 I contacted the user who pulled the packages to install it on Debian Testing and it happened to me the link with the update.
Installation
The installation process should be identical to what I describe in this post. However, I briefly repeat the steps here with the new link:
$ wget http://cloud.github.com/downloads/mockturtl/Cinnamon/cinnamuffin-1.3.1-i386-wheezy.tar.gz
$ tar -xzvf cinnamuffin-1.3.1-i386-wheezy.tar.gz
$ cd cd cinnamuffin-1.3-i386-wheezy/
$ sudo dpkg -i *.deb
If any dependency errors occur, please run:
sudo apt-get -f install
