I was connected with emacsclient and I guess I closed the lid of my
laptop ? Anyway, a few hours later I found that emacs had crashed.
Here's the backtrace:

Program received signal SIGPIPE, Broken pipe.

Lisp Backtrace:

"funcall" (0xbfffc560)

Is there anything that can be done about this ? (I unfortunately closed
the gdb session.)
