Python-2.5beta1 crash

[Robin Becker]

I'm testing ReportLab against Python-2.5beta1 and am getting some kind of 
problem as below

=======================================================
C:\Python24\reportlab\test>\python25\python runAll.py
.C:\Python24\reportlab\test\test_docstrings.py:54: ImportWarning: Not importing
directory 'C:\python25\reportlab\tools\utils': missing __init__.py
   module = __import__(mName)

   module = __import__(mName)
....Fatal Python error: non-string found in code slot

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
=======================================================

First off there may be a bunch of other C extensions involved including PIL, but 
I built them all against this beta. What should I do to refine the error? Do I 
start with trying to establish which of the tests is guilty or build from source 
in debug mode and attempt to find the problem from below.
