The same is already done for QWebView. On some web sites, we would still crash though. The crash is due to r40160 which triggers all timers to fire after everything was deleted. 204241 6 51658 commit-queue 2010-03-25 14:59:02 -0700 Comment on attachment 51658 Patch Rejecting patch 51658 from commit-queue.
