First, try to store them as integers if possible (i.e. size, date,
etc.), that should reduce memory usage already.

BTW1: You're leaking the list store in xa_main_window_set_list_interface().

BTW2: Remember to use fixed column sizes for the tree view, otherwise
it'll take too long automatically layout 60k rows.
