Knetworkmanager estoira ao iniciar.. como resolver isto?

[Gocho]

Bem, a historia começa quando andei a brincar com um tal de DBUS durante uma tentatica para instalar o kpowersave, e agora o knetworkmanager recusa-se a funcionar.
É este o resultado do crash:
(no debugging symbols found)

E então? Gostaram? Alguem sabe como resolver esta trapalhada? Já desinstalei e tornei a instalar, mas não resolve nada. Cumps

Bem, parece que não é só o kpowersave.. O firefox simplesmnte desaparece quando tento aceder as funcionalidade de algumas extenções, e está um pouco lento. Acho que no fim de semana vai haver direito a um reinstall do sistema
