The program 'gnome-settings-daemon' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 3208 error_code 8 request_code 149 minor_code 7)
  (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.)

$ kill %1

Log attached.

BTW, there's no need to enable TCP connections in gdm to do this. xtrace
works just fine using Unix sockets, which is what the -d :0 specifies,
after all.
