Sailfish WebView: Signal LinkClicked sleeps sometimes

[hanswf]

The signal “LinkClicked” does not fire sometimes. Here an example (from SDK Help):

import QtQuick 2.0
import Sailfish.Silica 1.0
import Sailfish.WebView 1.0

ApplicationWindow {
    initialPage: Component {
        WebViewPage {
            WebView {
                anchors.fill: parent
                url: "http://butenunbinnen.de"
                //url: "http:de.wikipedia.org"
                onLinkClicked: {
                    console.log("OnLinkClicked!")
                }
            }
        }
    }
}

When clicked at a pic the new page is loading. But the signal “linkClicked” is sleeping well.
For the second url, the signal works.
Tested with Javascript on or off. SDK target is EA-armv7hl 4.3.0.12.
