[issue19097] bool(cgi.FieldStorage(...)) may be False unexpectedly

[Guido van Rossum]

Guido van Rossum added the comment:

PS. Simple repro:

import cgi; bool(cgi.FieldStorage('logo', u'tux.png'))

This reveals it's been fixed in Python 3 -- it raises TypeError there as it should.  (But __nonzero__ should be deleted, and if someone adds __bool__ they should make sure it raises the same TypeError if self.list is None.)
