Lines 92 to 105 in 133cc3b

	def next(self) -> str:
	assert not self.empty(), "Cannot pick clip from empty pool"
	# find a clip that is not in the recent history
	idx = random.randrange(0, len(self.clips))
	while idx in self._history:

	# add to recent history
	self._history.append(idx)
	if len(self._history) > self._history_len:
	del self._history[0]
	return self.clips[idx]

is not working or _history_len has an incorrect value.
