[PyQt] Another wierd bug with QtWebKit

[Karthik Tharavaad]

Thanks for replying Phil, thats a great point which I didn't think about.
However 2 points
 - Even if the QWebPage does not parent the QNetworkAccessManager, shouldn't
it still hold a reference to it and keep it from getting deleted?
 - Even if the behavior is intended, under no circumstances should my
example program1 crash Python.exe the way it does right now. Is there
something wrong with the error handling code?
