Browser crashes on www.techcrunch.com

[GoogleCodeExporter]

From user:

 There seems to be a problem with the www.techcrunch.com. Most links clicked on will crash the browser. If the link is directly entered in the addressbar, no problem. If the same link is clicked in the site - crash.

-------------------

Confirmed - to check ...

• Changed state: Started

[GoogleCodeExporter]

QtWeb Build 3.5.59

As a workaround, in Qt 4.7.0 source file 
"c:\Qt\4.7.0\src\network\access\qhttpnetworkconnectionchannel.cpp" added 
condition to avoid NULL pointers, this removes browser crash, but this 
particular page "hangs-up", however the browser is still operational with other 
pages

void QHttpNetworkConnectionChannel::allDone()
{
 .....
    if (!reply)
        return;

    // while handling 401 & 407, we might reset the status code, so save this.
    bool emitFinished = reply->d_func()->shouldEmitSignals();
.....
