The related patch extends the autolaunch feature with an installation 
directory limited session bus.
This feature is required for multiple kde installations. It is enabled 
by using the session bus address "autolaunch:scope=install-path"

in 
http://websvn.kde.org/trunk/kdesupport/emerge/portage/win32libs-sources/dbus-src/dbus-src-1.3.1.py?view=log
there is a line
self.subinfo.options.configure.defines = "-DDBUS_ENABLE_XML_DOCS=OFF 
-DDBUS_USE_EXPAT=ON 
-DDBUS_SESSION_BUS_DEFAULT_ADDRESS:STRING=autolaunch:scope=install-path"

change it to

self.subinfo.options.configure.defines = "-DDBUS_ENABLE_XML_DOCS=OFF 
-DDBUS_USE_EXPAT=ON -DDBUS_SESSION_BUS_DEFAULT_ADDRESS:STRING=autolaunch"

and recompile dbus-src.
I guess we need a dbus client config file to be able to set this without 
using an environment variable.
