It is running, just something isn't right until I restart it. Strace just tells me it's broken.
Dbus is running right after I boot:

After I "sudo /usr/local/etc/init.d/dbus restart" hp-scan works as expected. The "your app is buggy" position doesn't hold much water when it works after dbus is restarted.
