Hmm, I used to propagate these errors until Philippe told me not to
(or at least that's how I understood it). I'll be happy to do it
either way (and the new API makes it really easy to propagate errors),
but I worry that I don't fully understand when to propagate errors and
when not to.
It makes sense to me to propagate errors from *_realize() and
error_abort on failure to set simple properties, but I'd like to know
if Philippe is on board with that.
