We don't initialize privateBrowsingEnabled parameter when creating the process. 2. When exiting private browsing, there is a good chance that NetworkProcess would learn about this while there are still requests in flight that have the private browsing bit enabled, and it will crash when trying to use the just-deleted private browsing session. 892498 1 202615 ap 2013-05-22 12:45:53 -0700 Created attachment 202615 proposed fix 892518 2 202615 beidson 2013-05-22 13:39:59 -0700 Comment on attachment 202615 proposed fix View in context: https://bugs.webkit.org/attachment.cgi?id=202615&action=review Seems fine.
