apt-get install libcanberra-gtk0 solves the problem for me. Weird, others solved it by removing this package?

GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported. Gtk-Message: Failed to load module "canberra-gtk-module" The fix/workaround appears to be installing libcanberra-gtk3-module, or removing libcanberra-gtk-module, which is only being installed as a recommendation for transmission-gtk (in this case): % aptitude why libcanberra-gtk-module i libcanberra-gtk0 Recommends libcanberra-gtk-module % aptitude search '?depends(libcanberra-gtk0)' | awk '{print $2}' balsa gnome-panel gnome-session-canberra gnubg gok libbrasero-media1 libcanberra-gtk-dev libcanberra-gtk-module libcanberra-gtk0-dbg libcheese-gtk18 metacity transmission-gtk wallch xchat-gnome I think that libcanberra-gtk0 should not only recommend the Gtk 2 module, but also the Gtk 3 one. So the "Recommends: libcanberra-gtk-module" should become "Recommends: libcanberra-gtk-module, libcanberra-gtk3-module".
