QListWidget regression when showing texts that do not fit on screen

In Qt 4.6 beta 1 there is a regression regarding texts that do not fit on screen.

If the text of a item does not fit in screen the text is cut and ... is added to it at the end.
The problem is that the horizontal scrollbar is not removed and moreover when you use
the horizontal scrollbar to scroll you end up discovering empty space after the "..."

This happens both in S60 and Linux

The attached code shows the problem.
