I solved that bug: the thing is that on debian testing fresh install the version of it is: Package: gnome-screensaver Version: 2.26.1-1 while gnome-session package and gnome-settings-daemons ar of older versions.
Fix: Install gnome-sessions and gnome-settings-daemon the same version as gnome-screensaver I did it from Sid packages and istalled 2.26.. versions of those three.. After reboot all works fine...
