That's fixed in 0.0.2, right?

Well, anyway, I changed the line in FileStorage.py as follows:
    # Use 0.5 GB partitions because that's what fits on a CD.
    defaultOps = PartitionedFileOperations(
        DefaultPartitionNamingStrategy(partlen=40000))
    #    DefaultPartitionNamingStrategy(partlen=2L**29))

...so I could try and provoke a split, but, now, when I try to add
objects, I get:

Error Type: CorruptedDataError
Error Value: 41904222L
