Application: plasma-desktop (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-29-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
I went into the activities menu and clicked add widget. It crashes plasma everytime. I have a clean install of Ubuntu (not Kubuntu) and have only installed the package kubuntu-desktop and few others (pmccabe, g++, and valgrind)

The crash can be reproduced every time.

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