Bug 277848

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Linux Mint 10 KDE

-- Information about the crash:
- What I was doing when the application crashed:
Installing updates via the "script manager" dialogue. Had selected an item to install (which it did, successfully) and I returned to the main script manager dialogue to search for more. When I clicked on another item (or more specifically, the information button for said item), Amarok crashed (bringing up another crash reporting assistant dialogue), followed by Plasma, which automatically restarted itself.

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