Binary package hint: compizconfig-settings-manager

Compiz crashed when im using compiz plugin: Opacity, Brightness and Saturation.
Emerald is already turned on.
Im try to set a window specific settings to opacity, when im in a dialog where i can specify the opacity_matches, im click on grab button and the crosshair appear, then when im used on any target the dialog gets the target, but after a couple of seconds new dialog pops up with error: Sorry CompizConfig Settings Manager closed unexpectedly. But looks like CompizConfig Settings Manager still working.
