I do not think that this is a segfault, as there is no core dump in /var/crash, unless something catches the signal? If so, then it shouldn't, as Ubuntu has apport to detect and upload crashes.
In my case, this seems to be a result of shutdown failing. I click the shutdown button, nothing happens, I click it again and it says "Failed to receive a reply from the session manager. Session manager must be in idle state when requesting a shutdown."
(xfwm4:2042): libxfce4ui-WARNING **: Disconnected from session manager.
** Message: using fallback from indicator to GtkStatusIcon
** Message: xfsm-shutdown-helper.c:1472: Using ConsoleKit to Stop
