-- Information about the crash:
- What I was doing when the application crashed:

I was not doing anything that should have generated any kind of notification and none was shown.  I do have Kontact running, so it's possible it generated a notification of some kind.

-- Backtrace:
Application: KNotify (knotify4), signal: Aborted
