[precise] Compiz slide-switcher blocks Unity edge reveal

Description: Ubuntu precise (development branch)
Release: 12.04

Within compiz: Enabling slide switcher blocks Unity's edge reveal although there is no apperent reason: no conflicts in key/mouse/screen assignments or the like....(hotkeys to the standard switcher and other possible potential trouble was disabled of course.).

Disabling the slide switcher immediately enables unity edge reveal again.

Further testing didn't reveal extra information except that the errand behaviour is predictable and rock solid :-)
