Our App, all of the sudden, started throwing errors from fragment. A lot of different lines, but definitely the stack is always the same:

(about 50 different lines with the same stack)

Since it comes 100% from Google code there's nothing we can do about it, unless of course someone could explain what " no event down from INITIALIZED" means...
