Hi Bart,

You might be able to avoid the problem by locking and unlocking the Qt library
mutex when creating each listview item:

  qApp.lock()
  QListViewItem(self.win.ListView1, "bleh")
  qApp.unlock()

This seems to work for me using PyQt 3.3.2 and Qt 3.0.5.

Phil, you advise calling the PyQt API from one thread only.  Do you see any
inherent problem in calling the PyQt API from a second thread if the Qt library
mutex is properly locked/unlocked when doing so?

Paul
