Code review comment for lp:~rodrigo-moya/unity/indicators-a11y

Seems ok, just some nitpicks:

83 + return (AtkObject *) pia;
287 + return (AtkObject *) piea;

why don't use the usual gobject macros ATK_OBJECT (pia)?

Anyway, then, when I tested it, I found this warning messages:

I used a custom script, but I also see them using accerciser.
