Turns out I didn't remove all index files.  After I did (dovecot.index +
dovecot.list.index) the assertion has gone away.  Interesting side-note:
after removal of the indices, some of my mailboxes showed new emails
from long ago, that I hadn't seen previously.
Now, from the first look and sizes, synchronisation seems to have
succeeded after a night.
