No, this is supposed to be impossible with QT. All QListViewItems have the parent
QListView, which has the chatview itself as a parent. When the chatview is
destroyed, so is the listview, and so are all the listview items. At least that is
how it is supposed to work.

It shouldn't have any effect, because as said above, all the LVI items should
be deleted when their parent is.

This part of the code has certainly not changed since 0.6, so it should be
easy to duplicate using HEAD. Maybe valgrind can help.
