genaxmodule and mozilla activeX control

Has anyone tried to use the new genaxmodule.py
in 2.5.1 with the mozilla activeX control from
www.iol.ie/~locka/mozilla/mozilla.htm

I tried:
python genaxmodule.py {1339B53E-3453-11D2-93B9-000000000000} mozwin

Traceback (most recent call last):
   File "genaxmodule.py", line 42, in ?
     main(sys.argv)
   File "genaxmodule.py", line 32, in main
     axw = wx.activex.ActiveXWindow(f, clsid)
   File "G:\soft\Python23\Lib\site-packages\wx\activex.py", line 220, in __init__
     newobj = _activex.new_ActiveXWindow(*args, **kwargs)
wx.core.PyAssertionError: C++ assertion "wxAssertFailure" failed in contrib\activex\wxie/wxactivex.cpp(320): m_ActiveX.CreateInstance failed

The ActiveXwrapper sample in 2.4.2 works.
