You are leaking both the returned GSList* and the data in each of its elements here, since atk_text_get_default_attributes() is transfer-full.

So, you should use a GOwnPtr<GSList> for that least, although you would still need to make sure that both the AtkAttribute structs and the gchar* pointers inside them (name, value) are freed before returning from this function.

Good point. Applied suggestions.

Thanks for considering those. The patch looks good to me now.
