KDE Platform Version: 4.7.4 (4.7.4)

-- Information about the crash:
- What I was doing when the application crashed:
I had selected the "Run Command" item from the main menu.  That opened at the top of the screen where I had positioned a second toolbar or panel.  When that did not run the command I entered, I closed it and selected the Application Launcher Menu widget I had added to the panel, and the crash occurred.  The screen blanked for a split second, and then everything looked fine.  Yum Extender was running on another workspace and it was fine.

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