Application: plasma-desktop (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.4
Operating System: Linux 3.8.0-28-lowlatency x86_64
Distribution: KXStudio 12.04.1

-- Information about the crash:
- What I was doing when the application crashed: I right clicked, selected 'add widgets' then on 'get new widgets' then it crashes. I already had downloaded a couple of widgets, then suddenly this happened, reproducable even after reboot now.

-- Backtrace:
Application: Plasma bureaublad-shell (plasma-desktop), signal: Segmentation fault
