KDE Platform Version: 4.10.00
Qt Version: 4.8.2
Operating System: Linux 3.2.0-37-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed: When attempting to open the menu activities and try to open the marrow of widgets, the screen is all black, playing the message that plasma crashed.

In all attempts the same problem occurred during the event were open firefox, dolphin and application that is not part of the system the ubuntu one.

- Unusual behavior I noticed: Light waged by clicking on the above menu, followed by black screen

- Custom settings of the application: Ubuntu One installed and running in the background, LightDM installed and running in place of the KDM, Used Air theme the environment.

The crash can be reproduced every time.
