As said, I don't see this. A good recipe usually starts with
"emacs -Q".
Oops, it seems to me, that something was messed up on my host.
I've removed all stuff related to Emacs and rebuild from current
source tree. And this message is gone. Sorry for noise.

Sorry again, but this message is gone because of the workaround in

my init.el: (global-eldoc-mode -1) I just forget about this.

As I said, I've completely clean my host from all stuff related to Emacs

and rebuild it from current source tree. The problem remains. Even

starting if I start Emacs as: emacs -Q --no-site-file --no-site-lisp.

I've toggle-debug-on-error and got the following backtrace:
