-- Information about the crash:
- What I was doing when the application crashed: open the opened applications
overview by moving the mouse to the left up corner
- Unusual behavior I noticed: KDE was closed the LightDM screen was shown for a
second and then KDE reopened ( with all running applications opened), the
application overview now doesn't work anymore
The crash can be reproduced sometimes.
