I hope this experience helps someone else. I pushed the SS 4.7 update (without wiping) only to have buggy behavior and poor performance - a clear candidate for a clean install. I ran bkapps, backed up my phone with Nandroid, and wiped. After reinstalling SS 4.7 and running rstapps the only issue I found was that google talk would not log in for anything. The repeat error I received was: "Google Talk authentication failed". What finally worked for me was *not* using rstapps to restore my account information on a clean phone. I installed SS 4.7 fresh, then used the standard account setup wizard when the phone booted. Only then did I run rstapps to recover all my other data. This worked perfectly and I'm now running 4.7 smoother than any ROM I've ever used. I'm not sure if there is any bug in restoring the applications or if this was unique to my situation, but I hope this helps out someone else.
