I'm trying to upgrade from 2.4.3 to 2.5.0, but I'm getting the weird 
error below when I start Zope:

 /home/samba/zope.temp# python z2.py -D
 ------
 2002-02-21T15:05:40 PANIC(300) z2 Startup exception
 Traceback (innermost last):
  File z2.py, line 495, in ?
  File <string>, line 1, in ?
  File /home/samba/Zope-2.5.0-src/lib/python/Zope/__init__.py, line 37, in ?
  File /home/samba/zope/lib/python/ZODB/FileStorage.py, line 243, in  __init__
    (Object: /home/samba/zope.temp/var/Data.fs)
  File /home/samba/zope/lib/python/ZODB/FileStorage.py, line 1886, in read_index
 ValueError: min() or max() arg is an empty sequence

Notes:
1. Everything fine in 2.4.3
2. Default database of 2.5.0 works fine
3. I've compacted the database just before trying to transfer it

I can send my Data.fs file, but since it is very big (40Mb compacted) I will just send it if you request.
