[mod_python] [SPAM] fixuphandler problem with mod_python-3.3.0b

hi,
I encouter a problem with mod_python-3.3.0b after installed it with mod_python-3.3.0b.win32-py2.4-Apache2.2.exe.

my fixuphandler in not founded anymore, although it's always there (D:/mydir/fixuphandler.py).
after installing again mod_python-3.2.10, every thing works fine again.
Here in the browser output (PythonDebug On):
