NullReferenceException crashing the application simmilar to #257

[xitac]

Hi, we're using version 1.5.3.5, and from time to time, we get the exception with the stack trace from below. I noticed that every time, just before this happens, we get STATUS_IO_TIMEOUT connection status. Then, on retrying the connection, the app crashes. Setting higher responseTimeoutInMilliseconds to SMB2Client.Connect helps, but doesn't seem like a good permanent solution.
