[ZODB-Dev] bug in slicing keys of BTrees

[Steve Alexander]

I've found this odd bug in the BTrees that is with Zope 3.

I haven't verified it yet for the Zope2 version (if that is different).

 >>> from Persistence.BTrees import OOBTree
 >>> b=OOBTree.OOBTree({'a':1})
 >>> b.keys()
<OOBTreeItems object at 0x81557c8>
 >>> b.keys()[:]
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
IndexError: 2147483647
 >>> [i for i in b.keys()]
['a']
 >>>
