plasma-desktop (0.4) on KDE Platform 4.9.97 using Qt 4.8.4

- What I was doing when the application crashed:

I was adding the gmail-plasmoid to the desktop (also happens when adding to system tray) when the desktop froze for about two seconds before crashing

- What I was doing when the application crashed:

Added the veromix widget to the desktop and it crashed. Something similar happend after upgrading to Raring, but think it was related to the python script engine for plasma (which is fixed now).
