To further test it, I tried with python2.4:

$ python2.4
Python 2.4.2 (#2, Nov 20 2005, 17:04:48)
>>> import bsddb
>>> bsddb.__version__
'4.3.0'

Works fine with 10 people and 100 sources:

$ python2.4 RunAllTests.py
----------------------------------------------------------------------
Ran 4 tests in 6.475s

OK


And fails, just as it does for you (same traceback),
with 100 people.
