Then it gets complicated, the problem seems to be Dbus' configuration.

There should be a session.conf under /etc, if not, then the dbus-daemon
is using defaults which, if I remember correctly, changed 2 or 3
versions ago to being restrictive (of course they call it "secure"),
that is: don't allow anything to connect to Dbus, unless specified on
the configuration.

I might be wrong, haven't used Dbus in a while.
