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

Browsing the web using Firefox. 

I had logged in a few days earlier, and the laptop had gone through several sleep/wake cycles. Konsole, Chromium, and Firefox had been open most of that time, and Ocular and Emacs were open at the time.

-- Backtrace:
Application: KDE Dæmon (kded4), signal: Aborted
