I have kind of bad news:

My reproducer recipe does not work anymore, today.  What I formerly
did was start Gnus in one session until an #.newsrc.dribble# appeared.
Then I started another Emacs session, and also started Gnus, got the
autosave file warning, replied with 'n', and the error was signaled.

Worked yesterday, no longer does.

Any idea?
