Ubuntu crashes when "Login as another user" is selected
Here is the sequence of events. The computer is turned on, and User A logs on to Ubuntu. After some period of time the screen saver kicks in. User B comes along and selects "Login as another user" from the locked screen. Ubuntu immediately crashes and displays this screen (see screen photo below). At this point the computer is totally locked up does not respond to input from the keyboard or mouse.
I installed Ubuntu a couple of weeks ago, so it is relatively new. The problem described above happens about half of the time, and other times when "Login as another user" is selected it works just fine.
Here are the contents of /var/log/syslog from the time of the crash...
