Do not exit if the accessibility bus disconnects
Do not exit if the accessibility bus disconnects

We should not exit if, for instance, the accessibility bus's daemon dies as
a result of the session ending; we should let GNOME's logic kill the
application in that case.  Also prevents the application from crashing if
atk-bridge sends bad data that causes the daemon to disconnect us.
