What do you mean, Waldo?

There's one option in libdbus-1 to quit the application if the connection 
breaks, but as far as desktop applications go, it's pretty dangerous. 
It's off by default.

The bindings should provide a higher-level interface to trigger a graceful 
exit (saving files, etc.). Applications that are security-sensitive could 
reconnect instead [also handled at a higher-level].
