fail to start X, unknown tag standard_session_servicedirs

[frederic heem]

Hi,
After installing dbus 1.0 on a CentOS 4.4 (which is a rhel4) and rebooting, X 
failed to start and I was stuck with a console login and vi. 
dbus-daemon complained about the tag "standard_session_servicedirs"
Fine that it's not aware or it must not abort for this reason. It shall be 
robust enough to handle unknown tag.
Beware that upgrading dbus was can screw up the whole system.
