I ran into this issue as well. Make sure that your app is PUSHing and POPing...For me, the issue was that the app would never POP and this creates a duplicate key warning like you see above.

Yep, there is certainly more guard logic that could be written into the pushing/popping actions. In a full application these state changes would likely be more complicated and involved; you'll want to make those decisions on a per-app basis.

Closing due to age, feel free to re-open if need be.
