You still didn't tell what is your Emacs version :-(

I'm guessing it's 21.2 or some such, since that version (and all older
versions) had a bug in handling entries like "foo/" (meaning ignore
the directory `foo') in completion-ignored-extensions: they wouldn't
ignore these directories.  You will see that "CVS/" is already in
completion-ignored-extensions.

This bug is fixed in the CVS, so a future version will be free of it.
