I have found the offending code...he said sheepishly. In the __init__.py file I had the following: def initialize(context): ... import traceback; traceback.print_exc() instead of: def initialize(context): try: ... except: import traceback; traceback.print_exc() My thanks goes out to all who helped. Later, Mike

After some further investigation I have found that a product that I am developing is causing the error to appear. The product appears to work fine in zope. I can add it, create objects with it and the objects are persistent. Can someone give me some advice on how to go about debugging my product to identify the offending code? The error appears in the following environments:

SuSE 8.2 -- Zope 2.6.1 WinXP Pro -- Zope 2.7.x

Thanks, Mike
