The simple QML snippet below causes a crash, even though all it does is changing the URL.

I also get this, e.g. when changing URLs in a simple "browser":
```
import QtQuick 2.0
import QtWebKit 3.0
import QtWebKit.experimental 1.0
Rectangle {
width: 500
height: 500
TextInput {
id: location
height: 20
width: parent.width
text: "http://www.google.com"
onAccepted: {
webView.url = location.text
}
}
WebView {
id: webView
y: location.height
height: parent.height - location.height
width: parent.width
experimental {
preferences.developerExtrasEnabled: true
}
}
}
```

The Qt port has been removed from WebKit, resolving this bug.
