How does this work out with object_property_add_alias? It can fail and returns an error, so it should be called from realize, but it adds a new property on the object, so the property won't be useful if it can only be set after realize has added it. It seems like everyone calling object_property_add_alias passes &error_abort, so I suppose that is the get-out-of-jail card for reporting errors from init... Thanks, Andrew
