Comment 1 for bug 43962

Similar problem. The error message doesn't come up if I wait about 10 minutes before logging in.

~$ sudo /etc/init.d/dbus restart
 * Stopping NetworkManager dispatcher [ ok ]
 * Stopping NetworkManager daemon [ ok ]
 * Stopping DHCP client manager... [ ok ]
 * Stopping Hardware abstraction layer hald [ ok ]
 * Stopping system message bus dbus [ ok ]
 * Starting system message bus dbus [ ok ]
 * Starting Hardware abstraction layer hald
<Here it sits for a couple of minutes, so I guess that's where the problem is> [ ok ]
 * Starting DHCP client manager... [ ok ]
 * Starting NetworkManager daemon [ ok ]
 * Starting NetworkManager dispatcher [ ok ]

During the restart, gnome-panel stops responding. killall gnome-panel gets it going again, but it takes about a minute. Gnome-panel is also v slow on log-in, even if I wait for a while before log-in.
