You are trying to mix two thread implementations. This is possible, but
see the notes on threading in the PyQt HTML documentation.

I'd recommend just using the Qt thread classes.

If you want to use any of the Qt threading classes, make sure you are
running PyQt v3.2 as they were fundamentally broken in earlier versions.
