Did you fix it finally??

Also I getting a related (I think) error Crashed: com.apple.main-thread 0 libobjc.A.dylib 0x7e74 object_isClass + 16 1 Foundation 0x1cf88 KVO_IS_RETAINING_ALL_OBSERVERS_OF_THIS_OBJECT_IF_IT_CRASHES_AN_OBSERVER_WAS_OVERRELEASED_OR_SMASHED + 44 2 Foundation 0x18384 NSKeyValueWillChangeWithPerThreadPendingNotifications + 268 3 AVFCore 0x5c55c __67-[AVPlayer _createAndConfigureFigPlayerWithType:completionHandler:]_block_invoke_2 + 172 4 libdispatch.dylib _dispatch_call_block_and_release + 24

Any solution to this?
