bug#19138: Emacs crashes

[Andreas Enge]

With current emacs-24.4 of git 0276f69, the following crash occurs:

I start emacs, which seems to launch a gtk version.
Then I click on the first icon in the upper left, labelled
"Specify a new's file name, to edit the file".

The program crashes with the following message:
(emacs:22810): GLib-GIO-ERROR **: No GSettings schemas are installed on the system

I am using guix on top of debian with kde.

This fix causes two unfortunate side effects on my system:

* When launching Emacs from the WindowMaker dock, the dock icon stays
  gray forever (indicating that the program is launching).  However, it
  should be noted that the WindowMaker dock handling of Emacs 24.4 was
  already somewhat broken before this, although in a different way.

* The window title is now ".emacs-real@<hostname>".

Regarding the window title: it occurs to me that it would be better for
our wrapper script to pass the original program name as argv[0].  This
could be important for some programs whose behavior depends on argv[0].

I fixed this by removing my old emacs dock icon, putting a new one back
in, and then editing its settings to change "-emacs-real" to "emacs" in
the launch commands.  So I guess most of the problems above were because
of the stale item, and the only remaining issue for new users will be
having the launch commands be "-emacs-real" by default.

I worked around this by setting Emacs.title in ~/.Xresources.

I don’t know how the WindowMaker dock works actually.  I tried it in a
VM, but there are only two icons: one for the WindowMaker preferences,
and one for xterm.  If you have an idea how this works, I’m all ears.

Good idea.  Done in 2ed11b3 in ‘core-updates’.

Thanks,
