Can you post the stacktrace of the exception? If it's happening at print(red.toInt()), it might be that the Smart Contract is sending data that is too big for ints. Did you check the data with another Ethereum implementation to see if the value fits in 63 bits?
Otherwise, it's certainly a bug in the library. It would be helpful to have the stacktrace, the contract abi (or at least the event definition) and the encoded event data (event.topics and event.data) in that case. Thanks!
