Replying to this bit separately, since I think it's another topic.

The difference between D-BUS and X is that you're using the IPC for lots
of different purposes. I think there are a fair number of those purposes
where handling errors makes sense. There are others where it doesn't.

But for example, to me if gnome-session or Metacity aborted on error
while talking to an app, that would be broken.

If an app exited in the absence of a session manager, though, then that
might be reasonable.
