Hi,

I finally figure out why kxmame mysteriously crashes using qt 3.3.5. This
is because QListView::clear() method doesn't reset d->highlighted to NULL.

This means that after a few tries of clearing and repopulating the item
list, d->highlighted might point to an invalid location. When
QListViewItem::takeItem is called, d->highlighted is used and causes
crash. Remarkably, due to the way it's coded, this bug doesn't appear in
Qt 3.3.4.

I included the fix patch below for your information. I don't want to
subscribe to another qt-devel list to send this bug info. So if anyone
here can help sending this patch to the proper place, please do.

Thanks a lot,
Toan
