-- Information about the crash:
- What I was doing when the application crashed:
Reparei que por defeito que a composição não estava activada. Reparei que o Latte-dock não era apresentado correctamento por causa da falta da activação da composição (opengl) a transparência não era apresentada na barra. 
Ao verificar a casa de activação da composição no painel de controlo do KDE / Ecrã e Monitor verifiquei que a  composição não estava activada.
Ao activar a casa e aplicar o kwin estoirou. Verifiquei tambem que estoura sempre.

The crash can be reproduced every time.

-- Backtrace:
Application: KWin (kwin_x11), signal: Bus error
