[power]: gnome-settings-daemon crashed with SIGSEGV in screensaver_vanished_cb()

I had an clean install and updated system with Saucy-Proposed repository enable. I instaled some packages [screen-resolution-extra (0.15ubuntu1), python-xkit (0.5.0ubuntu1), fakeroot (1.19-2), dkms (2.2.0.3-1.1ubuntu4) and libvdpau1 (0.7-1)] and I was seeking for un bug, and noticed that dbus-daemon was taking all my processing (more than 100%), I tried to sudo killall dbus-daemon from tty3 and the system crashed. I turned off my laptop with the power button, and when I returned to the unity desktop, this bug report appeared.
