bug#17957: 24.3.92; Bad interaction between "emacs --daemon" and "desktop-save-mode"

[Benjamin Riefenstahl]

Receipe from a command line:

  mkdir /tmp/t
  cd /tmp/t
  cat > .emacs <<EOF
    (add-to-list 'window-system-default-frame-alist '(nil . ((menu-bar-lines . 0))))
    (desktop-save-mode 1)
  EOF
  HOME=$PWD emacs --daemon
  emacsclient -n -c

Now in Emacs execute the commands 

  desktop-save
  kill-emacs

Restart Emacs with

  HOME=$PWD emacs --daemon

The menu bar has disappeared and a get an error message:

  Error (frameset): Wrong type argument: number-or-marker-p, nil

Thanks for the nice report.

Following my change for

http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17693

this issue does not seem to occur any more.

That is a good change, I think, I was wondering if the behaviour was
intended.

OTOH I still think there is another issue.  An entry in
window-system-default-frame-alist for terminal type nil should not cause
changes for a graphical display, regardless what desktop.el does, right?
Unless desktop.el messes with these variables in the wrong way.  So
there is either a problem with the interpretation of these variables or
with desktop.el setting them wrong.  And it is not a problem caused by
an .emacs.desktop saved with the previous version.

(I'm going through old bug reports that unfortunately got little response at
the time.)

I tried following the recipe (in Emacs 28), but I was unable to
reproduce the problem.  Are you still seeing this issue in more recent
versions of Emacs?

The original issue was fixed.  I was somehow wondering about a more
fundmental problem, but I can not at this time reconstruct what it was
or why I thought that the patch was not sufficient for that (I assume we
were talking about #c9f7ec736b here).

I think we can just close the bug and assume that any other issues have
been or will be dealt with when they cause actual problems.

Thanks, benny

Yup.  I'm closing this bug report, then.
