Package: mailman3-web
Version: 0+20180916-2~bpo9+1
Dear Maintainer,
After upgrading from earlier python2-based packages, I ran into this problem of
Whoosh databases between python2 and python3 being incompatible:
$ sudo -u www-data /usr/share/mailman3-web/manage.py update_index_one_list
exam...@example.com
Indexing XXX emails
Exception in thread Thread-1:

UnicodeDecodeError: 'ascii' codec can't decode byte 0x80 in position 4: ordinal

The solution is to remove /var/lib/mailman3/web/fulltext_index/ and run:
$ sudo -u www-data /usr/share/mailman3-web/manage.py rebuild_index
This is mostly FYI for other stretch-backports users. As mailman3-web is not in
stretch, it's probably not worth it to bother handling this when upgrading
packages.
