Try for example M-x gnus-read-ephemeral-emacs-bug-group RET 34671 RET.
For me, it triggers this backtrace:

I don't seem to be able to reproduce this on latest master (see revision
after my signature).  Here's what I tried:

0. HOME=$(mktemp -d) emacs -Q
1. (setq gnus-select-method '(nnnil ""))
   C-j
2. M-x gnus RET
3. M-x gnus-read-ephemeral-emacs-bug-group RET 34671 RET

Which revision of master are you on?  Are you able to provide a more
precise recipe?

Thanks,

I'm on git revision 568af1e5822086f2457b6e98a22624b8138aa72f.

emacs -q
(require 'gnus-group)
M-x gnus-read-ephemeral-emacs-bug-group RET 34671 RET

is enough to trigger this. I can't reproduce with your recipe, although
if I do "q" (quit gnus) "y" (confirm quitting) in between your steps 2
and 3 then I can trigger it. As I said in another thread, I'm just
getting started using gnus. Is gnus-read-ephemeral-emacs-bug-group not
supposed to work if gnus isn't open?

I think it ought to work, yes. Would you try the attached patch and let
me know if it solves the problem?

Thanks,
