this is the *system* bus which is supposed to be started by calling

 sudo launchctl load  -w /Library/LaunchDaemons/org.freedesktop.dbus-
system.plist

*once* after KDE was installed.

yes. so far, so good.

usually, this should already be handled by the postinstall scripts in the 
bundle.

yes, this is the *session* bus. according to https://community.kde.org/Mac it 
should also be launched with "sudo"... but that portion hasn't changed in 2 
years, so let's assume this is not the reason.

@aaron: did you already see this happening before september 2014? if not:

@thomas: can this be related to one of these commits:
 - 4802
 - 4803
 - 4822
 - 4834

another idea: is it possible that installing the RKWard bundle several times 
(upgrades) and therefore running the postinstall script several time somehow 
messes this up? i still don't have the best understanding of how these mac 
bundle packages actually work, as apple used so many different formats and the 
documentation is... sparse.
