Missing dependency (dbus-x11) for Zattoo 3.2.1

[ubu-for]

I use Feisty and tried to install Zattoo 3.2.1 but GDebi reports that the dependency is not satisfiable (dbus-x11).

I had no problem with version 3.1.1 and don't find dbus-x11 with Synaptic.

Any ideas?

Now I've found a rpm package (http://www.rpmfind.net/linux/rpm2html/search.php?query=dbus-x11), but every time I try to install the created deb package by alien, GDebi reports "program not installed". The new deb package has nearly half the size of the original rpm package.

Thanks in advance!
