[PyQt] Using a preview widget with a QColumnView

QColumnView steadfastly refuses to display a preview widget. Could 
someone else try running this code snippet and see if it works for you?

|import sys
||from PyQt4 import QtCore, QtGui
| app = QtGui.QApplication(sys.argv)
model = QtGui.QFileSystemModel()
view = QtGui.QColumnView()
label = QtGui.QLabel('HELLO')
Unless I'm missing something, navigating to a file should show the 
'HELLO' label in the right-most pane of the column view. Doesn't work 
for me, the pane is blank. I've confirmed that the updatePreviewWidget 
signal is being emitted.

(Python 2.5.4, Qt 4.6.0, PyQt 4.6.2, X11)
