Can't read Emacs manual

[Rodolfo Medina]

Hi to all Emacs users.

When I type `C-h r' the Emacs manual is not open, and I get the following error
message in the echo area:

        Invalid face family: ""

This is due to some code in my ~/.emacs, that I report.  Please help modify it
in order to solve the problem.  I have now Emacs cvs 23.0.91.1.  That code used
to work fine with Emacs 22.

Thanks in advance,
Rodolfo
