Martin, AFAIU it's used just to make sure that a dbus call originates
from a process on the same machine of the receiver. But, please, audit
the code if you have time for that, and report any misbehaving. We
have also implemented a fix in dbus that re-generates
/var/lib/dbus/machine-id at each reboot (despite I think it's not
necessary).

I think that any leak in dbus would have been found by now (dbus has
been around for several years), but I might be proven wrong. The code
is free software, available and distributed under GNU GPL2+ (and also
under Academic Free License 2.1). Literally anybody can read it. But
please, let's stop shooting in the dark.
