QListBoxItem is an abstract base class, you should be using QListBoxItemText.
In fact, I'm not sure why PyQt lets you instantiate it, it could be a bug in

There are situations in which you have two possible parents, so you first
create the child, and later bind it to either parent depending on some
information extracted from the child itself. Remember that it is very common to
subclass QListBoxItemText to store additional information.
