Error Reading Aware: comparison of Fixnum with nil failed

Does this help ?

----------------------------------------
This is my code, "socket" is a SSLSocket this is why it allows a Regexp in gets

`begin
    http_response[:http_headers] = WEBrick::Utils.timeout(3){
      socket.gets(/\x0d?\x0a\x0d?\x0a/, 4096) #\r?\n\r?\n
    }
  rescue Errno::ECONNRESET
    return nil
  rescue Timeout::Error
    LOGGER_SYSLOG_SYSLOG.syslog_error('e', 'Timeout when reading aware')
  rescue Exception => e
    LOGGER_SYSLOG_SYSLOG.syslog_error('e', "Error Reading Aware: #{e}")
    retry unless socket.eof? || socket.closed?
  end`

The error reads like this: "Error Reading Aware: comparison of Fixnum with nil failed"
Which means it comes from this begin\rescue block, but there is nothing inside it which would compare a Fixnum with nil, so, I suspect that gets does it ?
