This sounds really confusing, and i'm not sure how to help you debug. :/
when you say "recreated the entire database", do you mean you dropped
all tags and everything, and reindexed the entire datastore?

Does the thread that you were working with contain any sensitive or
private messages?  If not, can you isolate the specific files from the
maildir that compose the thread (e.g. with a manual grep) and try to
recreate the failure with a smaller maildir and dedicated notmuch
database?  I know this is tedious, but if you can do it and share the
maildir, then it would help other folks reproduce the problem and dig
into it further.

if i was debugging this locally and i had a dedicated maildir that
demonstrated the problem, i'd probably try to inspect the xapian
database (e.g. with xapian-delve).  There are several folks on the
#notmuch channel on freenode that can probably give pointers.

Sorry to not be more helpful,
