[Zope] Export/Import problem (...object broken doesn't...)

[sara]

Hi!
I am a beginner in this Zope world. I am having a 
problem and I could't find the solution searching 
the MLs archives.
I have exported a folder from my company Zope 
environment and I am trying to import it to my
home one, but all I get is:

The object broken doesn't support this operation

The error stack ends with:
path/CopySupport.py line 373 in _verifyObjectPaste
Copy Error: (see above)

Each time that I import/export from/to the same 
machine I don't experiment any problem, so I don't 
understand why my home Zope thinks that the company 
zexp contains broke object(s).

Does anybody have a clue on what is going on?

Thanks!
Sara
