Hi Gregor,
I'm not sure about the initial problem you're having, but I can help you
move FileStorages back and forth between 2.4 and 2.5 without "corruption".
To use the "corrupted" Data.fs that came as a result of using a 2.4 Data.fs
under 2.5, and then going back to 2.4 with the same Data.fs (actual symptom:
AttributeError: __call__ in line 171 of BeforeTraverse.py), use this small
MonkeyPatch product into your 2.4 instance:
http://www.zope.org/Members/mcdonc/Products/MultiHookMonkeyPatch . 2.5
inserts an instance of a class as a traversal function that does not exist
in 2.4; this patch creates a "dummy" class definition that allows you to
start the site again and delete the 2.5-specific objects that get added to
the root (temp_folder, session_data_manager, browser_id_manager).
