Yeah I haven't sent a fix for this yet. Downstream we have refactored
MR code and I wanted to get that upstream. With that this bug will
also get addressed. I was hoping to get that series but since some
optimisation is still pending investigations its getting delayed.

Will find out if I can fix this panic in meantime with smaller change.
Thanks for reminder.
