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

While installing VirtualBox 4.1 from a .deb file, the 20% low battery warning popped up then KDE crashed.  This was on a fresh install of Kubuntu 12.04 LTS.

-- Backtrace:
Application: KDE Dæmon (kdeinit4), signal: Segmentation fault
