This is not a bug, it is working correctly, as designed.
List multiplication does not *copy* the list, it replicates the reference to
the same list object. So [[0]]*5 does not make five different sublists, but the
same list repeated five times. Exactly the same as this:
a = [0]
mylist = [a, a, a, a, a]
