[PyKDE] crash after populating list view from separate thread

My my program starts up, I have to populate a list view.  There are many
items (over 5000), so I opted to do it in a separate thread.  Now, I'm
pretty new to QT (and KDE) programming, so I suspect I'm doing this
"wrong".  Please take a look and see...


class PopulatingThread(QThread):
   def __init__(self, prog):
      self.prog = prog

   def run(self):

class MyProg(KMainWindow):
   def __init__(self, *argv):
      KMainWindow.__init__(self, *argv)
      self.list_view = KListView(...)
      self.list_view_search = KListViewSearchLine(..., self.list_view)
      self.thread = PopulatingThread(self)

   def PopulateListView(self):
      for item in some_item_list:
         KListViewItem(self.list_view, item)


The problem is that when the thread finishes, the program crashes.  The
program doesn't crash if I call PopulateListView() directly from
__init__(), but then of course GUI locks up, progress bars don't completely
show, etc.

Any ideas?  Thanks for the help.
