Same for 'Open Location' dialog. Bug in Qt?

There are other cases, eg calls to Java, that could block JS. Something
has to be done.
That khtml currently even self doesn't check if it can close the window
proves the next testcase

<html><head><script>
  var win=open("", "xxx");
  var doc=win.document;
  doc.open();

doc.write("<html><script>setTimeout('self.close()',1000);alert(somevar);<\/script><body>");
  doc.write("</body></html>");
  doc.close();
</script></head>
<body></body></html>

Crash with backtrace this time.
