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.

There is something else going on here.  I can not reproduce this error, I 
always get "yes" in the buffer.  Futhermore, g_spawn_sync is a function in 
glib.  But Emacs never calls it, so where does it come from?  Can you run 
strace on your Emacs to see what it tries to spawn?  Since you leave out gconf 
and rsvg, glib does not get linked in, so the problem dissapears.

You should file a proper bug report so we can see how you configured your 
Emacs.  Also, what system do you run on?
