[wxPython] Python threads with wxPython

Can somebody offer some insight to why this program crashes on my NT box using Python 1.5.2
and wxPython 2.1.16? It appears to crash only threading.start() and EVT_IDLE are both
working. It usually crashes with "ceval: tstate mix-up", or "orphan tstate". It's not an
overload of threads, because as you can see, it crashes with just one thread started
(besides the main thread). Any ideas?
