Freedesktop.org vendors, please get the new DBus 1.2.4.2permissive release into your development stream as soon as possible, so DBus service developers and testers can help cooperate on fixing the broken services. Thanks!
Note: On my Fedora 10 system I got a lot of spam due to NetworkManager talking to HAL without this patch – so you likely want to get that one in at the same time.
