bug#14888: 24.3.50; Prompting for theme safety when restoring frames


From: chad
Subject: bug#14888: 24.3.50; Prompting for theme safety when restoring frames
Date: Wed, 17 Jul 2013 00:37:24 -0500

In GNU Emacs 24.3.50.1 (x86_64-apple-darwin12.4.0, NS apple-appkit-1187.39)
of 2013-07-16 on protip.local
Bzr revision: 109393 address@hidden
Windowing system distributor `Apple', version 10.3.1187
Configured using:
`configure --with-ns --enable-checking'

Important settings:
  locale-coding-system: nil
  default enable-multibyte-characters: t

When emacs prompts the user during startup (to ask if a theme is safe to
load) while it is trying to restore a previous session's window layout
(with the new features in desktop-save-mode), emacs sometimes never
actually creates a window.

Juanma has already changed the related code, but asked me to file
a report so that future versions can be checked. Using today's bzr
tip, I do NOT see the problem. Note that the revision info listed
in `Bzr revision' above doesn't match the revision that triggers
the problem.

To reproduce the problem, you will need a theme that emacs does not
consider safe. I tested with zenburn and naquadah, but any non-trusted
theme will do. Because the problem uses saved theme and desktop state,
it can't easily be reproduced with emacs -Q. Once problematic config
files are generated, they can be saved and reused later for testing.

   1.) Move personal configuration aside, including desktop file and
   custom file.

   2.) Place your non-trusted theme in the clean user-emacs-directory.

   3.) M-x customize-variable RET desktop-save-mode RET and enable
   desktop-save-mode. Save changes for future sessions.

   3.) M-x customize-theme RET and enable your untrusted theme. Mark the
   theme as safe for future sessions. Save changes for future sessions.

   4.) Quit emacs.

   5.) Manually remove the entry for custom-safe-themes from the clean
   user-init-file.

   6.) Restart emacs.
