[Interest] QtWebKit and open URL in new tab window

[Konstantin Tokarev]

Remaining question is why frame "_new" is not created from scratch after you close tab. This does not reproduce here,
and probably you are keeping around corresponding QWebFrame or QWebPage object after tab is closed, or just leak it.
