For the record, I solved the problem by following the instructions in

https://www.cyrusimap.org/imap/download/upgrade.html

specifically using the

reconstruct -G -V

command then nuking (ctl_conversationsdb -z) and rebuilding 
(ctl_conversationsdb -b) the conversations db for each user, then I used 
"squatter -v" to reindex all the messages.

I guess that ctl_conversationsdb in the two versions I tried (3.6.1 and 
3.8.1) has no safeguards against malformed mailboxes.

(BTW, the above is using 3.6.1, I removed the 3.8.1 version from backports).

This is fine and dandy for this small test server with 4 users, I'll 
have to devise a better way to migrate the production server.
