This is a bug in the program calling g_spawn_sync(); either don't request the exit status, or don't set the SIGCHLD action.

This is the error you get when you start emacs under X11 without having 
a D-Bus session daemon running.  See the release announcement for details:

See also /usr/share/doc/emacs/README.Cygwin.
