New crash information added by DrKonqi

plasma-desktop (0.3) on KDE Platform 4.5.60 (KDE 4.5.60 (KDE 4.6 >= 20100627)) "release 3" using Qt 4.6.3

- What I was doing when the application crashed:

I accidentaly added the aditional default panel on top of the sceen, where was the panel with systemtray an few widgets. So I remove both panels to recreate my Plasma layout.

- Unusual behavior I noticed:

After click on plasma button on the right top edge of the screen, Plasma crashed.
