We tested with 2.2.24, and were unable to reproduce the error. Can you
try again with 2.2.24?
Apologies for butting in, but I've been seeing exactly the same issue
post upgrade to 2.2.24 (from 2.2.18):

etc.
At first I assumed it was better at picking up corrupted indexes and
would reduce in severity over time. However, I've also seen that
attempting to force-resync or remove and rebuild indexes doesn't help -
it reoccurs on the same mailboxes.
Unfortunately I'm unable to reveal mails from affected mailboxes, so I'm
not sure how much help this is beyond a "me too".
