I haven't tried it, but probably removing the Xapian directories
and `lei reindex' with current public-inbox.git

I just pushed out some changes the other week which should make
it more robust against missing Xapian docs, but have yet to test
against non-existent Xapian.

I do wonder what caused it, AFAIK there's nothing in our Xapian
library usage which might cause this.  Perhaps an FS-level fsck
would be helpful.  Similarly, I would do git fsck and/or gc
and try the integrity_check pragma in SQLite just in case...
