First of all your software shouldn't crash. But even if it crashes you
can just configure the autostart behavior so it is relaunched if it
happens.

The problem with this is the following. Suppose an user has both
polkit-gnome and polkit-kde installed. Both packages provide a .service
file to start each authentication agent when someone calls into the
org.freedesktop.PolicyKit.AuthenticationAgent name on the session bus.
How should the message bus decide on which one to start? It can't.
