I was upgrading from 0.39.

Unfortunately, I cannot appear to reproduce the problem any more.
Re-upgrading to 0.40 now shows no problem, I've tried to explore the
range of things I may have done, but with no luck. I had to trash my
journals in order to downgrade, so there is some amount of state that
was lost which may be related to my inability to reproduce now?

For what it is worth, I believe the problem may have been caused by
something the 0.40 versions were sending.  As I was downgrading back
to 0.39, the downgraded 0.39 version kept dying with the same error as
long as one of the 0.40 versions was still up.

I did not know of the ms debugging when I was first investigating, but
looking through my old data, I have a trace with OSD debug set to 20
of the 0.39 version dying of the fault:
