This is a bug in the DIR file(s) distributed by Debian: it is not
allowed to have two or more menu items whose labels (the part between
the * and the first colon) are identical. The Info format disallows
that, and Info readers generally cannot cope with that.

That's one of the symptoms of the fact that two such entries cannot
live together.
I urge the Debian maintainers to fix that.

That's because Narrow is not a minor mode.

The text is hidden by Emacs display magic, not by narrowing.
