That is a very interesting bug.  I'm not sure it is actually wrong to
have a conflict record there, and deleting it would seem to just be
making things worse - it got there for some reason.

It is also harmless, so I wouldn't worry too much until we can fix up
dbcheck.  I may be back in contact for some details of the DB so I can
improve the test.
