[Pkg-mailman-hackers] Bug#1120645: mailman3-web: Deleting threads causes django errors

Thu Nov 13 20:32:29 GMT 2025

Package: mailman3-web
Version: 0+20240312-2
Severity: normal

Dear Maintainer,

Some spam came through on one of our lists and I wanted to delete the messages
via hyperkitty/mailman-web.  I select the thread, hit 'delete thread', get 
the confirmation page, then see a spinning waiting wheel.

In the logs I see:

Internal Server Error: /hyperkitty/list/<LIST_NAME>/recent-threads

DoesNotExist at /hyperkitty/list/<LIST-NAME>s/recent-threads
Thread matching query does not exist.

Request Method: GET
Request URL: https://<LIST-SITE>/hyperkitty/list/<LIST-NAME>/recent-threads
Django Version: 4.2.23
Python Executable: /usr/bin/uwsgi-core
