I get the same results as Tim using the 2.3.2 final version: Python
2.3.2 (#49, Oct  2 2003, 20:02:00) [MSC v.1200 32 bit (Intel)] on win32

In my 2.3.2 lib, the "return self.db[key]" line in __getitem__ is on
line 116 of __init__.py, not line 86 as in Richie's traceback.  I could
expect some changes between Python 2.3 and 2.3.2, but 30 lines seems a
bit much between minor bugfix releases.  Is that possibly an indicator
of a bsddb version mismatch?
