gnome-shell/js/ui/endSessionDialog.js
Giovanni Campagna 0d2eb76cee Ensure that all signatures are defined in DBus interfaces
The DBus JS binding will complain if the signature of a method
or of a signal is undefined, so we need to define it even if it
is an empty string, and we need to use the correct property name
for signals.
