i updated cvs today, and now I get the following errors, when I post
to a list:

Apr 25 11:54:54 2002 (20362) Uncaught runner exception: isinstance() arg 2 must be a class or type

when I test the email package as explained in the README with
PYTHONPATH=.; python2 tests/test_email.py I see the same error
.........................................................................................E.................tests/test_email.py:1638: RuntimeWarning: test_japanese_codecs() skipped
  warnings.warn('test_japanese_codecs() skipped', RuntimeWarning, 1)

Is this a bug or is there something wrong with my setup.
