New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- Custom settings of the application:

Using "Sleepy" plugin to close Amarok after so many minutes have expired. Occasionally, when Amarok closes, as programmed, the crash occurs. It doesn't happen all of the time ... possibly 20% of the time.
