Hey, what can I say? Did you actually try it on MS Windows?
This is 100% reproducible for me, using emacs -Q in 23.1.

And I don't think it _should_ be raising an error. You should be able to use any
wildcard expression (and that's what this is, in fact), and a Dired buffer
should be opened showing you the matches - even if there are none.

IOW, using `some-directory-that-does-not-exist' is no different from using
`*.jjjjjjjjj'. If there are no matches for the pattern, then you should get a
listing like what I wrote above - except the header info should be indented
properly.
