Don't really know why that file is there, but from this comment from
the code that creates it, it's not something you can rely in the long
term:

http://dev.laptop.org/git?p=sugar;a=blob;f=src/main.py;h=e78570769e8138c827e04c1a6af820c6ce712955;hb=HEAD#l53

Perhaps in the xo you could rely on this hardcoded value?

os.environ['DBUS_SESSION_BUS_ADDRESS'] = 'unix:path=/tmp/olpc-session-bus'
