     * wallets throws an exception, for backwards compatibility this read is wrapped in a try block to
     * silently fail. The test here makes sure the type of exception thrown from CDataStream::read()
     * matches the type we expect, otherwise we need to update the "key"/"wkey" exception type caught.
