[Zope] Tracker Export Problems

[Sebastian Sippl]

Hi,

I have tried to export an existing tracker to a different zope.
from zope v. 2.4.0 to 2.5.1

When i try to import it, i always get the error no module named splitter.

I also tried to export the whole content of the zope by copying the 
Data.fs file:

I can view the Tracker postings , but if i want to edit the state of a 
message i get the error:
attribute error: split

If anybody knows how to get the stuff working, please respond.

thanx,

Sebastian
