You'd have to case the data pointer back to an array of char *, which in C
is roughly the same as a pointer to char *. The easiest way would be:

    ((char **) list->data)[2]

But this question is quite inappropriate for the Gtk Developers list. This
is a list for discussion about the development _of_Gtk_itself_. You want
gtk-app-devel, but since this is a generic C question, it might not even be
right for that list.
