Bug 321134

Application: plasma-desktop (4.10.80)
KDE Platform Version: 4.10.80
Qt Version: 4.8.4
Operating System: Linux 3.9.5-1-ARCH i686
Distribution (Platform): Archlinux Packages

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

Typing in a text box on facebook.com in Firefox.  I hadn't clicked anything in the last few seconds before the crash, and nothing strange was happening on the desktop until Plasma flickered.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
