QObject::startTimer: QTimer can only be used with threads started with QThread in PyQt4

[Code_ReaQtor]

Hi,

I am working with QTextEdit with QCompleter using PyQt4. However, I am experiencing some problem upon application exit. Console shows
@QObject::startTimer: QTimer can only be used with threads started with QThread@

As a reference, the example from this "link ":http://rowinggolfer.blogspot.com/2010/08/qtextedit-with-autocompletion-using.html where I based it also produce the same output:

Thanks
