In what version of Emacs did you see that?  And on what OS?

Also, please post a complete recipe: do I type the above into the
*scratch* buffer, or into some other buffer, and what should be the
major-mode of that buffer?  Also, is the part inside [...] that
precedes the URL important for reproducing the problem?

Thanks.
