Hello,
Try the following:
1.- Start emacs (anyhow).
2.- Type `C-x C-f'.
3.- Now, from the minibuffer, type `C-h c' --> Here, Emacs prompts me
for a key to describe. OK.
4.- Type `C-n' (for example). --> Now Emacs should show me the
description of the `C-n' key (*), but that doesn't happens. Instead,
after a couple of seconds, the minibuffer comes back with the prompt
of the `find-file' command.
(*) Look at the Emacs manual, chapter 8 ("The Minibuffer"):

Thanks in advance. Dani.

For me, the message "C-n runs the command next-line" appears for a
second or two, then the "Find file" prompt reappears. This seems correct
to me.

I've just checked this in [1], and I can confirm that:
1. It works right from plain "emacs -Q".
2. It is still reproducible if you disable blink-cursor-mode.

Look in the *Messages* buffer, and you will see that the message is,
in fact, displayed, it just gets immediately overwritten.
I guess some incoming event causes some sit-for to exit early, or
something.

Fixed in trunk.

I have not seen the fix yet, but I certainly hope that the currently active
keymaps are used for this.
In particular, with the example given, the doc for `C-n' should list the command
it is bound to as being `exit-minibuffer', since the question about its binding
is being asked with a minibuffer keymap current, and that is the binding of
`C-n' in the minibuffer.
This is important. Emacs should always faithfully answer questions about itself
and its current state. When in the minibuffer, users should be able to ask and
get answers to questions about the current, minibuffer, state.
If for some reason some particular context/code needs to instead interrogate the
keymaps that were current before the initial command (`C-x C-f in this case), it
can do that (explicitly).
But a simple `C-h c' when the minibuffer is active should (must) DTRT and give
the currently active binding. Anything else would be counter the Emacs
philosophy of dynamic introspection. Emacs is not only self-documenting editor,
it documents itself in real-time. And nothing about Emacs is more important
than that.

It's apparently so.

?? `C-n' from the minifuffer doesn't exit the minibuffer. It seems to
be bound to `next-line', as reported if you do the experiment in the
original message.

Agreed, but that seems to be the current behavior. Try for example
[C-x C-f C-h c M-p]. Emacs will tell you that "M-p runs the command
previous-history-element". It looks ok to me.

Sorry, I was thinking that the request example concerned `C-m' (`RET'), not
`C-n'. (And of course for `C-m' the binding depends on which minibuffer map is
current. It is `exit-minibuffer' in some cases but not all.)

Good.
