* dbus/dbus-sysdeps.c (fill_user_info): On errors do not free
        the DBusUserInfo structure since this is passed into the function.
        This would cause a double free when the function that allocated
        the structure would try to free it when an error occured.

        * (bus/session.conf.in, bus/Makefile.am, dbus/configure.in):
        use /usr/share/dbus-1/services instead of /usr/lib/dbus-1.0/services
        for service activation to avoid 32bit/64bit parallel install issues
