All of your ~.bash_profile (on Linux) should have:

if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
     eval `dbus-launch --sh-syntax --exit-with-session`
fi

This is covered in the dbus-launch man page.  Note that you must use 
"eval" because you want it to take effect in the process which ran the 
script.

You also need to have the global dbus daemon running as user=messagebus 
group=messagebus.  This needs to be started at login with your startup 
scripts.  Run "ksysguard" in KDE 3 to see if it is running.  If you 
don't have that user and private group, you need to create them.

I am not familiar with the SlackWare startup script so you will have to 
RTFM on that.
