Hey, yeah it should be implemented like this:

func (l *Log) Read(off uint64) (*api.Record, error) {
	l.mu.RLock()
	defer l.mu.RUnlock()
	var s *segment
	for _, segment := range l.segments {
		if segment.baseOffset <= off && off < segment.nextOffset {
			s = segment
			break
		}
	}
	// START: before
	if s == nil || s.nextOffset <= off {
		return nil, fmt.Errorf("offset out of range: %d", off)
	}
	// END: before
	return s.Read(off)
}

I fixed a ton of issues that will be in the next beta, which should be out either late this week or next week.
