New crash information added by DrKonqi

plasma-desktop (0.4) on KDE Platform 4.9.4 using Qt 4.8.3

- What I was doing when the application crashed:
Click Show activity Manager followed by click on add widgets within activity manager.

- Unusual behavior I noticed:
The notification for a crash does not always show but the desktop will always flash black with two small widgets in the top left that look like they are for updates and dropbox.
