Application: plasma-desktop (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

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

I had gone to Panel Settings, and was attempting to drag the "Screen Edge" so that I could move the panel.
As soon as I had barely begun to drag, the desktop crashed.

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