-- Information about the crash:
after the first crash reported, now the same think appens to the system setting program when i click on the desktop setting icon, changing the show options to tree looks the crash comes when i click on the screen saver icon, by the way there is no support for visual effects, when with the kubuntu there was also if it wasn't  100% stable. 

The crash can be reproduced every time.

 -- Backtrace:
