[mod_python] Apache children crashing with mod_python 3.0 beta4

I'm trying out mod_python-3 beta 4 on FreeBSD 4.7.  Python is version
2.2.2 compiled from ports without threading support.  Apache is 2.0.43
compiled from ports with threads enabled, running with default
configuration (apart from mod_python customizations); mod_python is
the only non-stock module loaded into it.

Even though mod_python seems to be working fine, I am seeing the
following in the apache's error logs:

Fatal Python error: PyThreadState_Delete: tstate is still current
Fatal Python error: PyThreadState_Delete: tstate is still current

How likely is this due to a misconfiguration?  Any pointers?

Many thanks,
