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.
