Xorg crashed with SIGABRT after lockscreen

[Lázaro Zarê]

I'm having problems with the new lock screen of Ubuntu.
Every time the pc goes into idle and the screen is locked (hence the monitor is blanked as usual) and when I try to put my password, the Gnome lock screen appear mixed the new unity lock screen and the the screen freezes and the computer needs force reboot..
I took a picture of the bug.
Because this, I switched in compizconfig-settings-manager >>Ubuntu unity Plugin>>General>Lockscreen lightdm instead of Unity.
After that in the first time when screen locks, xorg crashed(and rapdly restarted) ocasioning this bug report

Sorry for my very Bad English

Porguguese version:
Estou tendo problemas com a nova tela de bloqueio do Ubuntu.
Toda vez que o pc entra em inatividade e a tela é bloqueada(consequentemente o monitor é apagado como de costume) e quando tento colocar minha senha , ao invés de aparecer a nova tela de bloqueio aparece a tela de bloqueio do Gnome e a tela congela e o computador precisa de uma reinicialização forçada.
Eu tirei uma foto do bug.
Por conta disso, eu troquei a configuração em compizconfig-settings-manager >>Ubuntu unity Plugin>>General>Lockscreen para lightdm ao invés de Unity.
Depois disso, na primeira vez que a tela foi bloqueada, o xorg travou(e rapidamente reiniciou) ocasionando esse relatorio de erro.
