Bug description:
Binary package hint: dbus
After running an upgrade on Ubuntu 10.04, I had several problems:
-Sound stopped working
-I could not access gnome-volume-manager or change the volume
-I could not start users-admin
-When starting amarok, it told me that some devices were missing and asked if
I wanted to forget about them permanently
-Shutdown and restart buttons in Gnome only logged me out
-Shutdown and restart buttons on the login screen did nothing
