This isn't a segfault, it's SEGPIPE, which just indicates that a socket has broken. This isn't fatal in any way, and more of a nuisance. Cyphesis will keep on running just fine (if you're in gdb just execute "continue").
You'll often get this when running a local server and starting up Ember, since Ember will just open up the socket to see if the server is alive, and then brusquely close it. Ember should behave in a better way, but since it doesn't cause any error I haven't put any effort into fixing it.
