This appears to be the same bug. The solution is to launch a DBus
session bus *before* starting emacs (or any other gtk3 programs for that
matter), IOW:
$ eval `dbus-launch --sh-syntax`
$ emacs-X11&
That gets rid of the warning, but emacs still dies after a few seconds
(no error message, no stackdump), unless I uninstall dconf-service. I'll
see if I can get more information by running emacs under gdb. I'd
appreciate any suggestions you might have as to where I should look.
I have some further information: The problem is related to the GSettings
backend. If I uninstall dconf-service and start emacs, I get a warning
that the GSettings `memory' backend will be used. Emacs then works
fine. If I reinstall dconf-service but set GSETTINGS_BACKEND=memory
before starting emacs, it again works fine. Does this provide any clue
as to what the problem might be?
Okay, I got it. dconf-service needs a GVfs implementation, but the
default provider (from the gvfs package) is currently only available in
Ports. That's what I get for trying to be minimalistic wrt the distro.
Of course, my gvfs package requires Avahi[1], so it may be an
interesting ITP; I'll try to do that next week, and hopefully this
thread will help expedite the review nonetheless.
In the meantime, try setting the GIO_USE_VFS environment variable to
"local"[2], which will allow dconf-service to work despite the lack of
gvfs. (Why this isn't done automatically as a fallback, I have no
idea.)
This doesn't do it. Emacs still dies after a short time. I don't know
if that means that there's something else going on, but I'll retest it
after you package gvfs. In the meantime, I'll continue with my
workaround of setting GSETTINGS_BACKEND=memory.
In case you (or anyone else) wants to experiment with this, you can get
my build of the emacs-24 pretest by running
setup.exe -K http://www.math.cornell.edu/~kbrown/kbrown.gpg
and adding http://www.math.cornell.edu/~kbrown to the list of mirrors.
