Created an attachment (id=166839)
 --> (https://bugs.webkit.org/attachment.cgi?id=166839&action=review)
VS project file to reproduce the bug

I already reported this bug to the QT bugtracker (https://bugreports.qt-project.org/browse/QTBUG-27303), but it was flagged "out of scope" there and I was told to report it here.
I'll copy the information, to make sure its all in one place:

This very simple test program does compile, but crashes with "..exe has stopped working" directly after starting it,
 iff the "view->..." line is activated.

-------------------------------------------
 #include <QtGui/QApplication>
 #include <Qt/qwebview.h>

int main(int argc, char* args[])
{
  QApplication app(argc, args);
  QWebView *view = new QWebView(0); 
  // view->load(QUrl("http://qt.nokia.com/")); // <-- crash
  view->show();
  return app.exec();
} 
------------------------

Environment:
Visual Studio 2012 RC (VS 11) x64
Windows 7 x64, all updates

I used a fresh VS project and added a main.cpp, linking against
 QtWebKit4.lib;QtGui4.lib;QtCore4.lib;QtOpenGL4.lib;

I'll attach the solution file and the resulting executable.

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