Application: plasma-desktop (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-27-generic x86_64
Distribution: Ubuntu 13.04

-- Information about the crash:
I restarted the computer and logged in. Then the screen remained black and the Crash Reporting Assistant appeared. Then the desktop etc were shown on the screen as usual (except for the window of the Crash Reporting Assistant, which is usually not shown). I recently installed the "Remember the Milk Plasmoid" -- I do not know if it is related to the crash of the Plasma Desktop.

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