Restarting or dying? If it's dying, it's a bug and should be reported.
I haven't had a crash in dbus in years, and I think pretty much
everyone agrees it's pretty stable nowadays. It even tries to handle
gracefully thins like out-of-memory errors and things like that.

If it's restarting, why on earth will someone restart the system bus
with active X sessions? If the dbus daemon is restarted, it has to
kick all the apps from the bus, including the session manager.
