[Tutor] shelve error

Hello!


Python 2.2's version of 'shelve' may depend on the 'bsddb' module.  On my
Linux systems, at least, I know that it has.


bsddb was buggy in 2.2, and was replaced in Python 2.3 with a more stable
implementation:

The notes don't talk about why the old 'bsddb' module was retired, but
stability seems to be the major issue:

This bug did also effect the Windows version too:

So definitely upgrade to Python 2.3.

It's probably not Microsoft's fault either here... bsddb --- and the
modules that depended on it --- was just broken in Python 2.2, period.
*sigh* Thankfully, things look better now in 2.3.


Hope this helps!
