Patch from Joe Eaton <jeaton@hostway.net> (SF#100741) to fix following problem:
There is a silly bug in the fall-back dumbdbm.py database package in
the Python 1.5.2 standard distro. This bug causes any changes to an
existing item to generate a new key, even when the key already
exists. After many updates, the .dir file used by dumbdbm grows to
a huge size, and can cause filesystem problems.
