Hyperkitty: AttributeError: 'NoneType' object has no attribute 'subject'
I'm getting a 500 server error with some threads in hyperkitty, e.g. this one: https://we.lurk.org/hyperkitty/list/tidal@we.lurk.org/thread/3IN5NFFFPVAQSRK...
The following appears in the log, any pointers much appreciated!

Hi Mark,
This may be related to our not clearing cache when deleting messages/threads. See <https://gitlab.com/mailman/hyperkitty/issues/160>;. If so, restarting your web server may help.
I tried restarting uwsgi but no dice. It's only affecting particular threads and I don't know of any threads being deleted so I think it's probably a different issue.
Best wishes
alex
I spotted a row in the hyperkitty_thread table that had a NULL starting_email_id, and no emails pointing at it. Deleting this row seems to have fixed things.
