I have reproduced the problem easily. I just switched the sound effects a few times and the switchboard plug seemed to become unresponsive. Switchboard itself survived and I was able to hit the home button and return to the main settings page. The executable path that crashed was /usr/lib/plugs/GnomeCC/GnomeCC. I got an apport alert that I will report as I don't know how to include the details of the crash on this bug.
