-- Information about the crash:
I had been attempting to kill a process from the S"ystem Actifvity" window.  I was asked for authentication, which I provided.  Nothing seemed to happen.  I tried again, and got the notification of the crash.  This may be a duplicate as indicated, since there were two efforts to kill a process within a short period, and possibly the second authentication request window was never seen.

-- Backtrace:
