[Zope] - BoboPos probem

[Thomas Heller]

I have an application mainly programmed within an external method.
This method is called with the 'self' parameter, so has access to the folder it is defined in.

I decided to attach custom data from within the external method to the self object.
This data was a list containing lists containing integers.
Everything worked well, but finally I discovered that 'cleaning up' Zope's database failed with an error. Trying to restart Zope failed miserably (traceback is attached).
It seems this has not been a good idea. What did I do wrong?
