Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed: I pushed the "new activity" the when I pushed the "add panel" button it crashed. I'm new to kde and my son said it might have did that because the default  panel button i selected was already active.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
