an obvious guess. However, I don't see, how this would be the case. If you 
look at rkward_startup.cpp, you should find it simply mimicks, what we had, 
before. In particular it tried to launch org.freedesktop.dbus-session.plit, 
but not dbus-system.plist.

Something causing this to be called twice is another idea, in fact. On your 
university mac, the error message is a bit more verbose: 

Oct 16 11:08:10 RKWard-iMac org.freedesktop.dbus-system[78533]: Failed to 
start message bus: Failed to bind socket 
"/opt/rkward/var/run/dbus/system_bus_socket": Address already in use
Oct 16 11:08:10 RKWard-iMac com.apple.launchd.peruser.505[78521] 
(org.freedesktop.dbus-system[78533]): Exited with code: 1
Oct 16 11:08:10 RKWard-iMac com.apple.launchd.peruser.505[78521] 
(org.freedesktop.dbus-system): Throttling respawn: Will start in 10 seconds

So dbus-daemon --system is already running, but the launcher is trying to 
start it again, fails, and tries again...

Interestingly, on the university mac, the error message starts appearing today 
at 11:08:10. That's shortly, after I started playing with it. Looking at the 
process list, you can see that the current dbus-daemon stared at 10:49. That 
process came up automatically, when I tried killing the previous dbus-daemon 
process. Well, I tried a whole bunch of other things in between, but can't 
attach a timestamp to those.

One thing to check may be what happens after a reboot. Does the message start 
appearing right away, or only after doing something KDE-related?

Regards
Thomas
