PollingListWalker is a very old compatibility hack that ListBox uses when you pass its constructor a normal list instead of a list walker instance.
This hack needs to be removed, and code that relies on it should be updated. https://github.com/wardi/urwid/issues/37 I'll need to either raise an exception when normal list is passed in, or change the default to use SimpleListWalker or SimpleFocusListWalker instead. The latter is friendlier but will cause some urwid programs to quietly stop working properly. Thoughts?
