Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Firefox 3.6.16 was open to google.com
2 Dolphin windows were open
Amarok 2.4.0 was open (using KDE 4.6.1)

I closed Amarok, and Plasma crashed.
