Hello . . .

As above, I received an error notification when I logged into KDE  SC 4.13.2. I followed the prompts but somehow I lost the wizard. I found this text in my home directory. Hope it helps. This is above my pay grade so I know nothing about the text!

Application: plasma-desktop (4.11.10)
KDE Platform Version: 4.13.2
Qt Version: 4.8.6
Operating System: Linux 3.13.0-30-generic i686
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
<In detail, tell us what you were doing  when the application crashed.>
I logged into KDE and the message showed.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Bus error
