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,
