Description of Problem:

Using the 2004-05-27 'snapshot' of Debian
Unstable, at GNOME startup, gnome-settings-daemon
fails to start and throws up a crash dialog (which
is totally uninformative). Trying to start it by
hand causes it to ponder for about 30 seconds then
it emits the following results:

-------------------
$ /usr/lib/control-center/gnome-settings-daemon  
                                                 
                            
** (gnome-settings-daemon:8557): WARNING **: Could
not activate the XKB configuration
The program 'gnome-settings-daemon' received an X
Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or
no such operation)'.
  (Details: serial 112 error_code 1 request_code 0
minor_code 0)
  (Note to programmers: normally, X errors are
reported asynchronously;
   that is, you will receive the error a while
after causing it.
   To debug your program, run it with the --sync
command line
   option to change this behavior. You can then
get a meaningful
   backtrace from your debugger if you break on
the gdk_x_error() function.)
-------------------

The selected GTK+ theme, font settings, etc. are
applied when it starts, and reset to the default
as it crashes.


Steps to reproduce the problem:
1. Upgrade to Debian Unstable
2. Start X with a Gnome session.

How often does this happen? 
Every time.

Additional Information:
$ gnome-session --version
Gnome gnome-session 2.6.1
$ /usr/lib/control-center/gnome-settings-daemon
--version
