If I restart zope then I can update OK for a while, but then after several hours the error comes back! zope 2.6.2 (with included python 2.1), CMF 1.4.2, plone 2.0RC5, RDFSummary 4.2p1 here's the traceback: xception traceback Time 2004/07/12 11:48:37.103 GMT-4 User Name (User Id) admin (admin) Request URL http://www.bowery.com/protest/News/bowery/update Exception Type TypeError Exception Value unbound method __init__() must be called with instance as first argument Traceback (innermost last): * Module ZPublisher.Publish, line 98, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Products.RDFSummary.RDFSummary, line 328, in update * Module Products.RDFSummary.RDFSummary, line 802, in parse_url * Module urllib2, line 135, in urlopen * Module urllib2, line 318, in open * Module urllib2, line 297, in _call_chain * Module urllib2, line 826, in http_open * Module urllib2, line 818, in do_open * Module urllib, line 805, in __init__ TypeError: unbound method __init__() must be called with instance as first argument
