Sorry, I should have remembered that.

Here is the backtrace:

Does it tell you something?

There is no such file in my home directory (except the one of No Gnus
v0.17). Do I need to disable the Gnus that comes with Emacs
explicitly, other than saying

(setq load-path (cons (expand-file-name "~/gnus-n0-17/lisp") load-path))

in ~/.emacs?

Yes, indeed, but in this case, that wouldn't be necessary, since the
problem only emerges in the new version ;-)
