Thanks a lot Marcos. I was using Jim Bublitz's
doc/examples/pyKHTMLPart.py and modified it from there. It appears to
me that parentWidget for the KHTMLPart is not 0:

class pyPartsMW(KParts.MainWindow):
    def __init__(self, *args):
        ...
        self.w = KHTMLPart(self, "HTMLart", self)
        self.w.openURL (KURL("http://www.kde.org"))
        domDocu = self.w.document ()
        html = domDocu.toString().string()
        ...

Then I got the error message:

terminate called after throwing an instance of 'DOM::DOMException'

where .toString() is called. Is there any other reason leading to this
other than the 0 values when initiate the KHTMLPart object?
