Bug 314234

Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
The terminal indicate that the installation process is still in progress.  But unfortunatelly it is stopped accidently when I dropped my pen to the space bar.
I log out, and try the desktop.  Then I know that my plasma desktop can't work properly.

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