You're code is causing a RuntimeError to be raised some where in a type checking call. Unfortunately because of old APIs in CPython that are not "allowed" to fail, CPython cannot continue to raise the exception, so it just prints that ugly error message and clanks happily along. The best way to avoid this is just throw away sys.stderr in code that is acting up like this. -- http://mail.python.org/mailman/listinfo/python-list
