Interesting.

So it looks like you have a Pile that contains no widgets, and yet
move_cursor_to_coords is still being called on it, like it's about to
take the focus.  I guess that could happen if your ListBox has no
selectable widgets in it, but I'm wondering if there will be other
problems with having a 0-height focus widget.

try adding:

    else: return False

after the for loop, container.py line 1001.  And let me know if things
continue on any further for you.
