bug#6336: Subject: 23.1; desktop suppresses *Warnings* buffer on start

[doclist]

With (desktop-save-mode 1) in .emacs the *Warnings* buffer is killed
after startup effectively suppressing warnings. To reproduce add

  (desktop-save-mode 1)
  (warn "foo")

in .emacs and observe that the *Warnings* buffer is killed after
starting emacs. 

Expected behavior: The *Warnings* buffer should not be killed.
