Take Browser demo software, and access http://techcrunch.com/ website, and keep clicking links there.
Soon you'll see browser crashed, and exception is thrown from here:

{
.........
// while handling 401 & 407, we might reset the status code, so save this.
bool emitFinished = reply->d_func()->shouldEmitSignals();
.........
Here "reply" variable is NULL and exception is thrown when accessing it.
Here is a stack trace:
