No, it's how dbus works. You kill dbus and Firefox crashes, and this is every distro I have tried it on. This is intentional behavior, because dbus is designed for DE users and if the Windows taskbar crashes, Windows will restart it. The idea is that if dbus crashes, your session is broken and your xdm or whatever should restart your DE.

If you are talking about the system dbus, it's the same program that is used to run a user-level dbus. I am not running the system-level dbus.
