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...
