reset-compiz-gconf crashed with GError in __main__: No D-BUS daemon running

[Carlos Soriano Sánchez]

After yesterday update, I restart and try to go into ubuntu unity 3D but, unity didn't start. The others programs are running normally.
In console I stoped lightdm and start lightdm. After I loged in as ubuntu 2D and everything works but a bug-report appears. So I am here.
Also I received this bug: https://bugs.launchpad.net/ubuntu/+source/ubuntu-sso-client/+bug/972276
