Application: plasma-desktop (4.11.1)
KDE Platform Version: 4.11.1
Qt Version: 4.8.5
Operating System: Linux 3.11.1-200.fc19.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Logged into user account - as programs were loading I ran a sudo yum update in Konsole. The Skype splash screen displayed just after I hit enter and as that was loading my Desktop went black and on return I had a notification that Plasma Desktop had crashed and a request to file a bug report.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
