pascal, if that is so, why is it listed as the FATAL error? Maybe just as you 
say, it doesn't find it, issues the FATAL error message, keeps going and dies 
somewhere else, but it is the last error I see. The strace shows this 
sequence:

(==) Using default built-in configuration (30 lines)

waiting for X server to shut down Dropping master 


[{WIFEXITED(s) && WEXITSTATUS(s) == 0}], 0) = 2370
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0      
--- SIGCHLD (Child exited) @ 0 (0) ---            
waitpid(-1, 0xbf9938fc, WNOHANG)        = -1 ECHILD (No child processes)
sigreturn()                             = ? (mask now [])               
<snip>

Then X just dies. Full strace at:
