Comment 7 for bug 310199

I found the problem: Using dcoonf-editor if you go in /org/gnome/desktop/sound and set in keys "event-sounds" and "theme-name" with the same values but set as user defined, not as default value, then you run the command /usr/bin/canberra-gtk-play --id="desktop-login" --description="GNOME Login" from the terminal you can see the error, but if you reset this two options with the default values (i.e. the same values, but now are the Default values) running the same command the problem doesn't exists
