Comment (by smcv):

 No, calls will fail after the service crashes or is stopped. If you add
 follow_name_owner_changes=True to the get_object() call, it *might* work,
 or not - it depends entirely on the D-Bus interface you're wrapping.
 That's why the dbus-python default is to not follow owner changes.

 This can only be fixed on a case-by-case basis, by someone who understands
 the API that's being wrapped.

 If the API you're wrapping is stateless, using follow_name_owner_changes
 will work.

 If you want to cope with crashes in a stateful API, you probably have to
 expose more of the detail of what's going on to the API user. For
 instance, invalidating objects when the service that created them crashes.
