Ok

Ok, sorry for the misunderstanding. Yes, StallyLabel overrides
get_name (I'm using my patch here [1]).

Well, as I said in my original mail, I found this issue making some
tests, in fact testing that my patch [1] was working. But right now I
don't need to call atk_object_get_name, but I found that I can't call
it making that tests. The purpose of the mail were check if there are
a way to call it, as I still need to check if this problem affects to
other ATK methods.

As in the end there are no way to do that, and in order to found
workarounds, I search a little on AtkObject, and the name is also
exported as a property [2]. I have used it and works with problem.

Thanks for all your help, and hints.

BTW: you still thinks that this is a problem with ATK, in the sense of
a bad name-policy?
