Exceptions on NSNull

[lowfreq2010]

Hello,

Hope that someone is watching this repo. I've got a strange problem. Our crashlytic has been reporting very hight number of crashes in OperationBufferImplementation.m – line 79 -[OperationBufferImplementation obtainBufferDataWithValidationBlock:] метод. Приложил скриншот со стектрейсом краша.

Подскажите как исправить данную проблему? Спасибо заранее
