TDE <-> Gnome conflict

Hi There, I just did a fresh install of wheezy inkl. Gnome (by choosing "desktop env., which by default is Gnome in wheezy/debian). I then tried to install TDE, which ends in this conflict: "The following packages have unmet dependencies: desktop-base-trinity : Conflicts: desktop-base but 7.0.3 is installed. kdeprint-trinity : Conflicts: foomatic-db-compressed-ppds but 20120523-1 is installed. The following actions will resolve these dependencies: Remove the following packages: 1) desktop-base 2) foomatic-db-compressed-ppds Leave the following dependencies unresolved: 3) foomatic-db-engine recommends foomatic-db-compressed-ppds | foomatic-db 4) gdm3 recommends desktop-base (>= 6) 5) printer-driver-min12xxw recommends foomatic-db" Isn't TDE ment to live in co-existance with other DEs (like most aof the other do to?)
